ABSTRACT:
A high efficiency gate driver circuit for driving a power switching device of a high frequency converter includes a series resonant circuit for making resonant transfers of energy between the input capacitance of the power switching device and a storage capacitor to achieve substantially lossless gate switching. An ac switch couples the resonant circuit to the junction between upper and lower switching devices connected in a half-bridge configuration. The upper and lower switches of the half-bridge function to maintain the power switching device in either an ON-state or an OFF-state, respectively, depending on the transfer of energy being made. Timing circuitry ensures proper gating of the switching devices relative to operation of the ac switch.
