摘要

本文提出了一种电压馈电/箝位高频感应加热准谐振逆变电路，该电路采用静态感应晶体管(B-SIT)进行软开关，并采用特殊设计的匹配变压器在移相功率调节策略下有效地工作于零电流软开关模式。采用新开发的B-SIT模块的电压箝位准谐振逆变器版本更适合工业生产工厂的现代感应加热和熔化电源。介绍了它的工作原理，包括控制策略，并讨论了它的特点。进行了详细的计算机辅助特性分析;对各种开环稳态工作特性进行了评估。

Zero-current soft-switched high-frequency induction-heating inverter using bipolar-mode normally-off SITs

The authors present a voltage-fed/voltage-clamped high frequency induction heating quasi-resonant inverter circuit which uses a static induction transistor (B-SIT) for soft switching and a specially designed matching transformer which efficiently operates at zero-current soft-switching (ZCS) mode under a phase-shifting power regulation strategy. This voltage-clamped quasi-resonant inverter version using the newly developed B-SIT module is more suitable for modern induction heating and melting power supply in industrial production plants. Its operating principle is presented, including the control strategy, and its distinctive features are discussed. A detailed computer-aided characteristic analysis has been performed; various open-loop steady-state operating characteristics have been evaluated.<>
