Three- phase rectifier

In this paper, a detailed three-step start-up procedure for the three-phase four-leg inverter in the AC Battery is proposed. In the first step, the DC-link capacitor is charged by the threephase bridge diode rectifier via precharge resistors, which are used to limit the charging currents.

The results of this research are explain about the number of loss energy in three phase rectifier is 21,6 Watt. In VVVF inverter and three induction motor, there are five samples. From analysis of the samples result that VVVF inverter has the highest efficiency 95,53% with loss energy 19,992 KW, which on 645 Volt about output voltage and 90 Hz about output frequency.
