A test facility for large scale inverter valve and pole using resonant circuit

This paper proposes a test method for single phase inverter pole which is the basic building block for large scale three phase inverters. Inverter poles for utility application need to be tested at full voltage and current ratings which reach thousands of volts and amperes. This paper proposes a novel method for testing large scale inverter valves and poles using a resonant circuit which allows testing of inverter valves and poles at rated current and voltage with relatively low AC power levels. The configuration and layout of the test facility is introduced and actual test results are presented.
