A single‐ended resonant‐type high‐frequency inverter using a static induction transistor (SIT) described in this paper can be performed as a zero current switching (ZCS) operation without dc reactor. The SIT high‐frequency inverter is a low‐cost one which has no transformer and it would be developed for a high‐intensity ultrasonic power supply and dc‐dc converter. The circuit operation regions, not only ZCS but also ZCS‐ZVS (zero current switching and zero voltage switching), were elucidated in the normalized plane. The characteristics of the inverter including the power control by frequency regulation were discussed. Furthermore, the switching characteristics in the transient‐state were investigated. These characteristics were substantiated on the basis of the numerical analysis and experimental results.
