The PMOS‐controlled thyristor (PMCT) was tested in a single switch configuration under inductive load conditions. The transient waveforms during turn‐on and turn‐off were observed such as the anode current iA, inductor current iL, anode‐to‐cathode voltage vAK, and gate‐to‐anode voltage vGA. The test circuit was operated for the power levels up to 390 W. These waveforms were obtained for periodic gate drive voltage. The measured turn‐on time was 0.255 μs at 270 V and the measured turn‐off time was 1.6 μs at 16 A. The measured storage time was 1 μs. The measured input capacitance of the MCT was 13.5 nF and the output capacitance was 66.7 nF. It was found that the input and the output capacitances were approximately linear. The turn‐off energy was 2.8 mJ, the turn‐on energy was essentially zero, and the conduction loss was 0.8 W. The MCTs can be used for high power applications.
