Abstract
Existing modular multi-level converters can be bulky because their submodule capacitors are comparatively large. To address this shortcoming in the state of the art, the present disclosure provides electronic power circuits and their use in power converters and in modular multi-level converters. The disclosed power circuits include connection terminals connected to electrically controllable bidirectional two-quadrant switches and to capacitors, as well as inductors that are magnetically coupled and operate to equalize voltages of the capacitors.
