摘要: An open-loop and closed-loop control method is proposed for a single-phase or polyphase three-point converter which connected to DC voltage intermediate circuit, having two series-connected main switches/inverse diodes between each connection load connection. The common junction point of the inner switches forms active clamped switch with an inverse diode outer center tap circuit. As result which, possible paths are formed connecting tap. Irrespective direction current, at least one (T5, T6) together provides circuit that can carry current deliberately through upper path, lower both paths, during null state.
