Abstract
Systems, methods, and devices relating to a DC/AC inverter. The inverter has a full bridge converter and an output filter with an integrated magnetic subcircuit. The subcircuit has main and auxiliary inductors and is designed to steer the current ripple of the inverter's output to the power semiconductors in the full bridge converter. By doing so, zero voltage switching is achieved by the power semiconductors, thereby mitigating switching losses. At the same time the current ripple in the inverter's output is attenuated.
