Progress Towards an MCT-Based 100+ KW High-Frequency Inverter

Abstract

Significant progress has been recently made in achieving a 100+ kW level inverter using high-voltage diffusion-doped MOS Controlled Thyristors (MCTs). These MCTs are the deliverables from a three year contractual effort to extend the MCT technology to devices capable of switching high voltages/powers. Preliminary test results have shown that a single device can control/turn-off at least 160 kW average power (burst), handle a surge (single shot) turn-on of 15.5 kA at 1720 V for a peak switched power of 26 MW, and can be operated up to 50 kHz. Additionally, series operation of 3 MCTs to 5 kV, and parallel operation of 3 MCTs to 300 A turn-off have been demonstrated. Future work will deal with construction and evaluation of a high average power inverter using these MCT switches.
