ABSTRACT:
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, power converter gate drive applications.
