Polyphase voltage converter |
摘要 |
A polyphase voltage type converter is provided in which ac switches are provided between a power supply and a diode bridge, and reactors that are star-connected are connected to input terminals of the diode bridge. The ac switches are turned on and off so that non-continuous current flows through each of the reactors, whereby input current is formed into a sinusoidal waveform even with a dc voltage lower than that of a conventional converter.
