40% of global energy consumption is the motor , under the impetus to improve the level of demand for factory automation , improve industrial motor power efficiency and performance requirements increase. In addition , solar PV has become incorporated into the global grid , the largest generation of energy , the cumulative installed base of 100 gigawatts , the next decade will be the fastest growing renewable energy.
For motor control and solar inverters , ADI four or five years from the start of planning , recently , ADI a brand new mixed-signal control processor ADSP-CM40x, high-performance , high-reliability motor control system and photovoltaic inverse transformer industry to promote lower system costs , and achieve a more affordable price advantage in the power grid infrastructure , and establish a new benchmark for the industry .
ADSP-CM40x series is a new generation of mixed-signal control processor ADI's family of application development for the precise control of the first member , it integrates precision (ENOB) over 13 industry 's only embedded dual -channel 16 ADC , equipped with a 24
0 M Hz floating point support ARM Cortex-M4
processor core .
ADI Marketing Manager Zhangsong Gang introduction, chose the Cortex-M4, mainly because ARM on power consumption advantages, a growing number of engineers are very familiar with this framework , the development cycle will be relatively short. The 240MHz clock speed and support for floating-point computing power , it is taking into account the future needs of industrial systems
All along , ADI has a profound accumulation , especially in the analog digital converter and DSP aspects , ADSP-CM40x give full play to the advantages of highly integrated ADC, larger RAM, harmonic analysis engine , SINC filter , PWM control and many extended interface and other functions , these functions via SIP technology package to achieve the perfect balance , not only has excellent performance analog conversion and conversion speed of up to 380ns , along with many other excellent features.
Technology as AD I have leading-edge , ADS P-CM4 0 x integrated 16-bit ADC accuracy at
2.6M sampling frequency can reach 13 or more, which
enhance the performance of the whole system is critical ; ADI unique harmonic
analysis engine technology for efficiency is important, it is primarily for the
future of PV inverter with charger , because for motor control , the need to improve the
efficiency of the algorithm is not only guaranteed but also interference in the
grid-side analysis , harmonic analysis can be very better monitoring and
interference suppression ;
Integrated SINC filter , it can be directly connected with the sampling resistive current detection system architecture for the isolated Σ-Δ modulator (AD
7400A/AD 7401A), but also cost savings to achieve the
same functionality FPGA needed and engineering resources ; ADSPCM40x retained
the three PWM control units, each unit supports 4 PWM output channels , which
can support dual-axis , three-axis control .
ADI provides current system evaluation board includes two CM
development kit for motor control applications 16 ADC input channels CM 408F development platform and for
photovoltaic inverters 24 ADC input channels . Which CM 408F oriented motor control demo board
high-voltage power systems , ADI also offers the option of PFC , use the power
management of the power factor correction to achieve higher energy efficiency.
ADI predict this feature in a future in motor control is mandatory .
