A ZVS DC-DC CONVERTER WITH SPECIFIC VOLTAGE GAIN FOR INVERTER OPERATION USED FOR 3-PHASE INDUCTION MOTOR OPERATION

Anil Kumar reddy.K, Sirisha.S

zero-voltage-switching (ZVS) dc–dc converter with specific voltage gain is proposed . The specific voltage is utilized for inverter operation for supplying 3-phase domestic load. It consists of a ZVS boost converter stage and a ZVS half-bridge converter stage and two stages are merged into a single stage. The ZVS boost converter stage provides a continuous input current and ZVS operation of the power switches. The ZVS half-bridge converter stage provides a high voltage gain. The principle of operation and system analysis are presented. The specific voltage is used to obtain a 200 volts Line to Line RMS AC supply through inverter operation. The supply is in turn used for a 3-Phase load like operation and speed control of 3-Phase Squirrel cage Induction motor.
