US Patent 11646732 Power module

A power module includes: a GaN transistor, an NMOS transistor, a first capacitor, a first diode and a second diode. The NMOS transistor is electrically connected to the GaN transistor. A negative electrode of the first capacitor is electrically connected to an anode of the first diode and a gate of the GaN transistor. A cathode of the second diode is electrically connected to a gate of the NMOS transistor. The power module further includes a power module control terminal electrically connected to an anode of the first capacitor and an anode of the second diode.
