Abstract |
A new capacitor-input type voltage source rectifier is proposed in this paper. The proposed rectifier is based upon 6-pulse diode rectifier with the addition of an auxiliary circuit. By proper operation of the switches of the auxiliary circuit, the input voltage waveform has 18-pulse characteristics and the input current becomes almost sinusoidal due to input ac reactors. The operating principle along with current analysis and input voltage waveform synthesis is described. The experimental results from a laboratory prototype verify the proposed concept. |
