Abstract
Various examples are provided related to operation of parallel semiconductors with different switching frequencies. In one example, a method of reducing conduction and switching losses in a high current switching circuit includes controlling two hybrid switches to conduct concurrently or alternately, each of the hybrid switches include a wide bandgap device and a silicon power device. Controlling of the silicon power device is at a first gate switching frequency and controlling of the wide bandgap device is at a second gate switching frequency, where the first gate switching frequency is lower than the second gate switching frequency. The silicon power device can be switched at a frequency of about 50 or 60 Hertz. The wide bandgap device can be switched at a frequency greater than 1 kHz.
