This paper discusses 40kHz IH inverter for indirect heating system and temperature control method of furnace using indirect heating system for aluminum alloy cast. Mostly, the heat treatment of aluminum alloy cast is technique of resistance heating. But the resistance heating furnace consumes more electrical power. For that reason, previous research provided indirect heating system using chain of mild steel. This method was done verification experiment using IH cooking heater. However, IH coking heater doesn’t have enough power for heat treatment. So, we attention to 40kHz IH inverter. In this paper, we describe heating performance of 40kHz IH inverter and temperature control method of indirect heating system using 40kHz IH inverter.
