A Performance Comparison of Series and Parallel Resonant Inverters in High-Frequency Applications

직렬형 및 병렬형 고주파 (공진형) 인버터의 특성연구

This paper presents a comparative analysis of two inverter power supply topologies for induction heating and melting applications. The comparison is based on criteria such as resonant condition, component ratings, minimum and maximum operating frequencies, operation under varying load conditions, inverter starting current, and diode reverse recovery time. The voltage source series/parallel resonant inverters are found to offer the best overall performance with respect to converter utilization.
