| Abstract |
To reduce switching losses in switching power converters resonant and quasi-resonant circuit topologies are getting more and more popular. To investigate the behaviour of IGBTs in a Resonant DC-Link inverter, a test circuit in zero voltage switching mode is presented. In this test circuit the semiconductor devices are stressed in a similiar way as in the real inverter. The switching frequency has been increased up to 100 kHz. Measured waveforms and results with IGBTs in the test circuit and a one phase Active Clamped Resonant DC-Link inverter are presented. A detailed investigation of losses in the semiconductor devices dependent on the resonant tank is given. |
