Research and Design on IGBT Induction Heating Power Supply
Induction heating technology having the advantage which traditional methods don’t have, such as high heating efficiency, high speed, controllable and easy to realize automation, is an advanced heating technology, and thus it has a wide range of application in the national economy and social life.
Parallel medium frequency induction heating equipment (1~10kHz) has the advantages such as low requirement on capacity of the power devices, easy to be paralleled to expand capacity, high adaptability to load and so on, so an increasing number of applications is received in induction heating power supply. Emerged in the early 80s, the entire control of power electronic semiconductor devices IGBT, with its high-speed, high input impedance, easy to drive, low on-state voltage drop and other outstanding features, has now a wide range of applications over the IF and VHF fields, and let the induction heating technology has a new leap   .The research on the induction heating power supply has been deepening in China. With the object of 100 kW / 8 kHz shunt induction heating power supply, the key technologies of the development of medium frequency induction heating power supply will be discussed as followed……
