1. A system for driving four-quadrant (4Q) switches of a power converter, comprising:
a transformer driver module;
a first gate driver module and a second gate driver module coupled to the transformer driver module via a first isolation transformer and a second isolation transformer, respectively, for receiving both switch signal information and power; and
a first bidirectional switch coupled to the first gate driver module and a second bidirectional switch coupled to the second gate driver module, wherein the first bidirectional switch and the second bidirectional switch are coupled to one another, and wherein the first gate driver module is configured to drive the first bidirectional switch and the second gate driver module is configured to drive the second bidirectional switch.
