Optimum Design of SCR Inverter for High-Frequency Induction Heating

SCR Inverter 고주파유도가열장치의 최적설계에 관한 연구

This paper describes the practical design of a SCR inverter which is suposed to be very much suitable for high frequency induction heating power source. In this design an optimum control technique was applied to maintain constant output power and constant power factor to various heating load by the use of frequency control. Some appreciable characteristics was obtained for some design guide of large ndstrial heating power sources by the test of the 3KHz, 3KW inverter which was designed in this study.

본논문은 고주파유도가열전원으로 주목을 끌고있는 SCR inverter의 실용적인 설계에 관한 것이다. 시간적으로 변화하는 부하에 대하여, 주파수제어방식에 의하여 출력과 역률을 일정하게 유지하도록 설계하여, 그특성을 측정검토한바, 만족스러운 결과를 얻었다. 시작시험한 inverter dir 3[KHz], 3[KW]의 것이었다.
