Abstract This paper evaluates the performance of a MOS-Controlled Thyristor (MCT) in a practical application. The {ital P}-type MCT is used in an AC Resonant Link Converter (ACRLC) which synthesizes three phase motor line currents from a high frequency AC (20 kHz) input. Based on the principle of discrete pulse modulation, the ACRLC operates as a current regulator. All switching transitions for line current wave-shaping occur at the AC link zero voltage crossings. Hence, in theory, switching losses are significantly reduced. This paper discusses the loss mechanisms, difficulties and solutions in using MCTs in ACRLCs. The MCT is critically evaluated, based on experimental results, on whether or not its present technology will allow the device to be utilized in resonant power conversion required for high efficiency, variable speed motor drives. {copyright} {ital 1996 American Institute of Physics.}
