Abstract
An integrated circuit includes a hybrid switch having first and second switching devices of different type therein. A control circuit is provided, which is configured to drive the first and second devices with respective first and second control signals having first and second unequal duty cycles, respectively, when the first and second devices are supporting a forward current in a first current range. The control circuit is further configured to drive the first and second devices with respective third and fourth control signals having third and fourth unequal duty cycles, respectively, when the first and second devices are supporting a forward current in a second current range outside the first current range. The first duty cycle may be greater than the second duty cycle and the third duty cycle may be less than the fourth duty cycle.
