Resonant gate drive circuits

Abstract From the Canadian patent

A resonate gate drive circuit for driving at least one power switching device recovers energy loss for charging and discharging the gate capacitance of the power , switching devices. The gate drive circuit uses a current source to charge and discharge the gate capacitance with a high current reducing the switching , loss of the , power switching device. The gate drive circuit comprises four semiconductor bidirectional conducting switching devices connected in a full-bridge configuration. An , inductor connected across the bridge configuration provides the current source. The , gate drive circuit may be used in single and dual high-side and low-side symmetrical , or complementary, …
