An LLC series resonant converter presents a viable opportunity for the realization of a DC solid-state transformer. As the DC-based power system increasingly garners the attention of academia and industry, the need for reliable, economical and efficient voltage transformation with galvanic isolation has emerged. The integrated gate-commutated thyristor (IGCT) is an attractive switch for such implementation because of its advantages over the insulated gate bipolar transistor, namely the lowest conduction losses in the class. This work shows that the IGCT can be easily implemented as a switching element in a resonant converter without the need for the protective clamping circuit. Resonant switching operation is demonstrated and supported by experimental data, and high efficiency is confirmed at high switching frequencies.
