Solid state circuit breaker

Patent image
CCDC ARL

A solid state circuit breaker includes a first terminal; a second terminal; a first wide-band gap field effect transistor coupled to the first terminal; a second wide-band gap field effect transistor coupled to the second terminal, wherein the first wide-band gap field effect transistor and the second wide-band gap field effect transistor are common-source connected to one another; and a bi-directional snubber device coupled to the first wide-band gap field effect transistor and the second wide-band gap field effect transistor. Such a solid state circuit breaker may also include a gate drive circuit coupled to the first wide-band gap field effect transistor and the second wide-band gap field effect transistor, where the gate drive circuit may comprise a voltage regulation stage and a drive stage.
