  • Parallel inverter scheme for separating conduction and switching losses
    Patent number: 9853570
    Abstract: In one example embodiment, a controller is coupled to a first inverter and a second inverter forming a parallel inverter scheme. The first inverter and the second inverter are configured to provide power to a load. The controller is configured to control the first inverter to operate according to a first operating state, while the second inverter is off, and turn off the first inverter before transition from the first operating state to a second operating state. The controller is further configured to control the second inverter to at least partially operate during the transition.
