Abstract
An integrated boost inverter circuit including at least one inverter stage having series connected high- and low-side switches having a common node. Each switch having an anti-parallel connected diode connected across the switch, which diode can be an external diode or an internal body diode of the switch; at least one inductor connectable in series between a voltage source and the node of the at least one inverter stage; a bulk capacitor connected across the at least one inverter stage; and a load being connectable to the node of the at least one inverter stage, wherein at every switching cycle, when the low-side switch of the at least one inverter stage turns-ON the respective at least one inductor is charged and when the low-side switch turns-OFF, the current in the respective at least one inductor re-circulates through the anti-parallel connected diode of the high-side switch into the bulk capacitor.
