The N - FETs (K720 as show in the circuit diagram) operate as switches controlled by signal from comparators. ... 2.4 True sine Inverter To operate an AC rated appliance, a device, which can convert the DC power supply of the PV system to AC power is required. Furthermore, in case inductive and capacitive loads e.g. fridge, fan, pump, etc. it is essential that the output of the inverter be pure sine wave.
