Abstract

This invention discloses a high-voltage frequency conversion device, which comprises a phase-shifting transformer and 3n power units, wherein every n power units are serially connected to form one phase, three phases are connected in the Y pattern to output to the load device, and n is a positive integer, wherein the secondary stage of said phase-shifting transformer is connected to said 3n power units and supplies power to the first-stage circuit of every power unit; said every power unit is an AC-AC converting circuit comprising two stages of circuits, wherein the first-stage circuit is a three-phase full-bridge comprising semiconductor power devices that can be turned off, the second-stage circuit is an inverter bridge comprising semiconductor power devices that can be turned off, and the two output terminals of said first-stage circuit are only corresponding to and connected to the two input terminals of the second-stage circuit. The high-voltage frequency conversion device provided in the embodiments of this invention is more environmentally responsible in addition to the benefits of lower cost, more stable performance, and smaller size and lighter weight.
