Abstract
A control system for a power inverter includes a gate controller, a gate drive circuit, and a hybrid switch power module that is integrated into a phase leg of the power inverter. The hybrid switch power module includes a first semiconductor switch connected in parallel with a second semiconductor switch. The gate drive circuit includes a gate driver, a first variable resistance circuit, and a second variable resistance circuit. The gate controller generates a first control signal for controlling the first semiconductor switch. The first control signal is selected to achieve a first switching transient in the first semiconductor switch. The gate controller generates a second control signal for controlling the second semiconductor switch. The second control signal is selected to achieve a second switching transient in the second semiconductor switch. The gate controller generates the first and second control signals to synchronize the first and second switching transients.
