ADSP-CM40x in Solar PV Inverters

Analog Devices provides high-performance signal chain solutions for today's modern, grid-tied Solar Photovoltaic (PV) Inverters. At the core of the system is the new ADSP-CM403 mixed-signal control processor that integrates a highly optimized, floating point ARM®-Cortex™ M4 capable of accepting up to 24 channels of analog sense inputs with 16-Bit precision A/D conversion. On-board memory has been included to support both the DC-DC boost stage and the DC-AC Inverter stage. The ADSP-CM403 integrates a highly capable PWM controller with up to 20 outputs along with ADI's advanced isolated gate drivers; optional Sigma-Delta shunt based current measurement for grid-side. Isolating between DC and AC sides as well as between machine and human interfaces is enabled with ADI's patented iCoupler® digital isolation technology. This solution represents a highly efficient and finely tuned platform that includes an abundance of ADI products including data converters, amplifiers, embedded processors, iCoupler digital isolators, and power management devices. Together with model-based control support and a specialized partner network, ADI has all the hardware, software and signal processing experience needed to simplify and optimize system-level Solar PV inverter designs.
