Idle power compensating device for switching voltage levels, has switching assemblies connected with respective bidirectional power semiconductor switches, and capacitors serially connected with each other

摘要

The device has switching assemblies (1.1-1.n, 8.1-8.p, 9.1-9.p, 10.1-10.p), where the switching assemblies (1.1-1.n) have bidirectional power semiconductor switches (2, 3, 4, 5). The switching assemblies (8.1, 9.1, 10.1) are connected with the bidirectional power semiconductor switches (2, 5, 3), respectively. The switching assemblies (8.p, 9.p, 10.p) have capacitors (17, 18, 19) that are serially connected with each other.
