Easy for you to resolve Clexane inverter schematic


Inverter is through the semiconductor power switches on and off function, the DC can be transformed into an AC power converting apparatus, the inverse transform is rectified. Direct current into alternating current through oscillation circuit, and the resulting alternating current through the coil voltage (in this case obtained a square wave alternating current). The resulting alternating current is rectified to obtain sine wave.

Car inverter circuit as a whole can be divided into two parts, each part to adopt a TL494 or KA7500 chips control circuit, where high-frequency PWM (pulse width modulation) switching power supply technology converted to 30Khz-50KHZ, 220V AC or so; second role of the circuit is to use the bridge rectifier, filter, pulse-width modulation and switching power output and other technology, 30KHZ-50KHZ, 220V AC or converted to 50HZ, 220V AC.

Many different types of off grid inverter  so select models and capacity requires special attention, especially in the solar power system, inverter efficiency is to determine the size of solar capacity and an important factor in battery capacity.

Divided by the output waveform, the inverter is divided into sine wave inverter and square wave inverter, sine wave inverter output is the same as the grid we use every day or even better sinusoidal alternating current power grid because he does not exist the magnetic contamination. Square wave inverter output is the poor quality of the square wave AC, and its positive maximum to negative maximum almost at the same generation, so that the load and the inverter with charger itself cause severe destabilizing effects. Meanwhile, the load is low, only the rated load of 40% -60%, not with inductive loads. If the load carried by too large, square-wave current third harmonic components contained in the content will flow into the load surname power increases, there will be serious damage to the load of the power supply filter capacitor.

We are in a "mobile" era, mobile office, mobile communications, mobile leisure and entertainment. In moving state, people not only need a battery or battery low voltage DC supply, but also need in our daily environment does not amount or lack of 220 volts AC inverter to meet this demand we.

Inverter is widely used in air-conditioning, home theater, electric grinders, electric tools, sewing machines, DVD, VCD, computer, television, washing machine, cooker hood, refrigerator, VCR, massage, fans, lighting and so on.

As we all know, the recent policy of state support for the introduction of photovoltaic industry, the domestic PV market is beginning to show "Red Sea" situation. Which, photovoltaic inverter is one of the most critical components. Can this core technology leader, become a test of China PV industry's core.

April 2013 Intertek German laboratory test results officially announced, Guruiwate new high efficiency inverter Growatt 20000 HE overall conversion efficiency up to 99%, into the global leading level. Industry sources, the current models in the same paragraph can only achieve 99% efficiency and Growatt two SMA, while Growatt can do a wider input voltage range.

Reporters learned that the side, in fact, this is not the first time Guruiwate global competitors with technical superiority so impressive. Back in 2010, Guruiwate once renowned in the world to get a PHOTON test A + rating, became the first Asian to get the assessment inverter enterprises. And in 2012, Growatt 5000MTL models get tested again in PHOTON double-A rating, competitors in the global display in front of the "Chinese inverter efficiency."

It is worth mentioning that this Guruiwate release of high-efficiency models and national planning of the "distributed generation" policy will coincide. Industry insiders explained that in a distributed power plant design and construction of photovoltaic panels taken into account during orientation, shelter, electricity and other issues, 20KW and below models will get more chance to show, especially when the subsidy policy oriented towards " generating capacity "direction close, similar to Guruiwate company released a higher conversion efficiency of the inverter will be distributed power station design undisputed best choice.

Market demand and the company's strength has been in production has been fully reflected.

Polysilicon industry export domestic photovoltaic inverter attention


The lowest price in the importing of polysilicon to 19 U.S. dollars / kg and excess capacity in the context of the domestic photovoltaic solar energy industry has begun to guide policy on export.

After going through the winter prices, the domestic photovoltaic solar finally usher in the dawn. China's "Twelfth Five-Year" period of photovoltaic solar power installed capacity target at 21GW, that is 21 million kilowatts. It is reported that the first photovoltaic "Twelve Five" period of installed capacity target of 5GW, last year raised to 10GW, after the end of last year raised to 15GW, this raised to 21GW, representing an increase of 3 times the initial value.

In this regard, analysts believe that the current situation facing the photovoltaic solar energy more severe, both the U.S. anti-dumping duty, another German solar program cuts, so this increase photovoltaic solar installation target aimed at stabilizing the overcapacity in the industry.

A brokerage believes that the domestic development of distributed power plants need to focus on policies to solve three problems areas, pattern links, technical aspects. At the same time, the current instability in the solar power itself on the domestic terms of the relative aging power grid will have a relatively large impact, even a threat to network security issues. To solve these problems, in addition to hardware upgrades from the grid, the solar power system side, especially the technical reliability of PV inverters is particularly important.

From the A-share companies in the photovoltaic inverter view, sun power, Kehua, Kstar RXPE, Kymmene technology and other companies involved in the PV inverter. Among them, the sun power PV inverter is a major company, 2011 sun power PV inverter to achieve revenues of 790 million yuan, accounting for 90% of the company's total revenue. PV inverter revenues increased 44.03% over 2010, while 2011 PV inverter shipments of 915MW, 2010 year 343MW.

Solar photovoltaic inverter industry or enter reshuffle


Studies have predicted that in 2014 the world's top ten manufacturers will be more Chinese enterprises.

"By the photovoltaic industry downturn, this year China PV-specific equipment orders will be reduced by 80%, while the domestic photovoltaic equipment market is expected to exceed 4.5GW." At the recently held second Intersolar China International Symposium on Chinese PV Industry Alliance Secretary Wang Bo to the outside world.

Wang Bo believes that the development of photovoltaic industry in recent years, mainly due to disorder, high dependence on foreign technology base and lack of innovation, and the rapid deterioration of the international trade environment, especially the growth of industrial manufacturing capacity far beyond the market growth, severe overcapacity of industrial development disrupted the normal rhythm.

As far as I know, with the entire PV industry situation changes, the PV inverter market structure is also experiencing a rapid transformation.

The next few years, both on the international market or the domestic market, the leading supplier of power inverters gridtiepowerinverteronline sort will change significantly. IMS Research forecasts also indicate that in 2014 the world's top ten manufacturers with the situation today is very different, there will be more Chinese and Japanese enterprises.

IMS Research senior analyst Xie Feng said, is expected in 2016, the inverter global shipments will reach 60GW, the market will reach $ 10 billion. He believes that the traditional sort of leader changes, depending on the situation in emerging market development.

Compared to the solar modules, the domestic share of the international market share of the inverter is still small. Xie Feng believes that from the quality point of view, the domestic inverter inverter with international brand gap is narrowing. From each of the power section of the inverter the whole, the stability of the domestic inverter conversion efficiency has been achieved great progress. IMS Research conducted inverter downstream user survey results also show that more and more customers began to accept China Western inverter.

However, Xie Feng said that the market share expansion requires more than just the product itself, but also depends on the business continuity of the brand positioning and continued into the market. Since China started late PV inverter brand, in 2011 shipments is only close to the global inverter 10% of total shipments. And the core components of the inverter http://www.gridtiepowerinverteronline.com/ (IGBT and MPPT) aspects are still not being implemented domestically.

Stored energy is the fastest growing PV inverter buyers demand


IHS Research report shows that the global PV inverter buyers, is the fastest growing storage needs. Although the technology is still relatively immature, but IMS Research for the global PV inverter four hundred customer survey showed that nearly a third of respondents forecast that by 2015, over 40% of their installed solar systems Enabling energy storage technology.

Germany, Italy and the UK respondents emphasized that for the future in terms of PV wind grid tie inverter  energy storage needs are more important than any other. When asked about the main driving force of energy storage factors, the most common answer is that customers batteries at lower prices, which helps reduce system costs, making energy storage economically viable. Over 60% of respondents said system including storage technologies raise the price 10-29% is "acceptable", even though nearly a third of respondents said they are ready to pay a higher premium.

IHS Power and Energy Research Manager Sam Wilkinson (Sam Wilkinson) said: "For photovoltaic systems, energy storage is becoming more and more important, if the supplier can deliver products that meet the industry expectations, photovoltaic energy storage market can remarkable development over the next two years. "this survey also asked customers about their use of micro-inverters, display relatively high price of this technology to become a widespread disorder.

But the survey also revealed that in 2012 over 2011, compared enabled micro inverters proportion of customers has increased ten percent. Respondents emphasized that they have the ability to block against the impact of additional design flexibility as the use of micro inverters most common reason.

Wilkinson said: "Because they offer the advantages and characteristics of the micro-inverter is becoming more widely accepted, but the price to make a major unfavorable factors, micro-inverters are not currently purchase most of the respondents said for them, the need to reduce the price of more than 50%, they only consider enabling.
