Abstract
A method, system, and computer-readable medium facilitate a soft switching technique for operating an inverter. In a full bridge inverter, a one of first set of transistors in the inverter may be rapidly activated and deactivated in pulses while one of a second set of transistor may be activated during a switching time period where the inverter matches the voltage and frequency of an AC grid. During a blanking time period between switching time periods, one of the second set of transistors may be primed before the other is activated during the next switching time period to prevent generating noise in the AC output of the inverter due to a hard switch.
