ABSTRACT:
One disclosed embodiment is a power conversion circuit including a power conversion bridge between a bus voltage and ground, including a switched node for supplying current to an output circuit. A driver section is configured to drive the power conversion bridge that includes a first section and a second section, the first section being between a negative supply voltage and ground, and the second section being between the switched node and a derived voltage below the switched node, the derived voltage being derived from the negative voltage. In one embodiment, the power conversion bridge includes a high side III-nitride switch and a low side III-nitride switch connected with the high side III-nitride switch to from a half-bridge. In one embodiment, the high side and low side III-nitride switches are depletion mode devices.
