Abstract
A high-frequency switch circuit is presented. The invention includes a pair of switches, a pair of inductors, and a pair of diodes. Inductors are electrically connected in series between the switches which are thereafter electrically coupled to a power source. Switches are electrically connected to gate drivers so as to control and coordinate the cycling of switches between ON and OFF states. Inductors are also electrically connected to an output thereby communicating a voltage waveform thereto. In some embodiments, it may be desired to electrically connect the inductors to an output circuit to further modify the waveform. Diodes are likewise electrically connected about the switches and inductors. The present invention is applicable to a variety of circuits having a totem pole arrangement of switches sequentially cycled ON and OFF, examples including but not limited to half-bridge, full-bridge, and hybrid configurations.
