Solar Inverter for Optimal Energy Conversion and Grid Integration based on onsemi Solution
The main components of this inverter system are the array of solar panels, the DC link capacitors and the inverter (DC/AC converter). Frequently DC-DC boost stages are used between the PV strings and the DC link. These systems fulfill two main functions: 1) elevate the output voltage of the PV string to the DC link operating level. 2) implement the MPPT (Maximum Power Point Tracking) function, that maximizes the power generated by the PV strings in different environmental and sun irradiation conditions. In situations where the PV string reaches the DC link operating voltage level, the DC/DC converter is bypassed (via a low VF diode) to maximize efficiency
