Abstract
Disclosed herein are methods, systems, and devices for providing power conversion between a direct current (DC) source and an alternating current (AC) power grid. According to one embodiment, a power converter device includes a transformer having a first winding and a second winding. The power converter device further includes zero voltage switch circuitry and zero current switch circuitry. The zero voltage switch circuitry is electrically coupled to the first winding, and configured to be electrically coupled to a DC voltage source via a first port and a second port. The zero current switch circuitry is electrically coupled to the second winding of the transformer and configured to be electrically coupled with an AC power grid.
