Patent ID: 11431331

Abstract:
A switching apparatus (20) comprises first and second current paths, each current path configured to be capable of conducting an electrical current, the first current path including a first switching element (28) connected in parallel with a first passive current check element (30), the switching apparatus (20) further including a switching controller configured to selectively control the switching of the first switching element (28), wherein the switching controller is configured to selectively switch the first switching element (28) at a first intra-current path switching speed to commutate the electrical current between the first switching element (30) and the first passive current check element (32), the switching controller is configured to selectively switch the first switching element (28) at a first inter-current path switching speed to commutate the electrical current between the first and second current paths, and the first intra-current path switching speed is faster or slower than the first inter-current path switching speed.
