| Abstract |
Medium frequency thyristor inverters are widely used for induction heating. They cover the frequency range from network frequency to (10-20)kHz. Vacuum tube inverters have served above 100kHz. There was a gap from 20 to 100kHz. No suitable power supply has been available although it is of particular interest for hardening processes. Inverters applying power transistors seem to be capable of filling the gap. The MOSFETs can even replace the vacuum tubes above 100kHz. This paper reports on the computer results of a 10kW, 20kHz current source inverter. The discussion of three current source inverters and their comparison are included. Two start-up procedure, design principles, control solutions are treated. |
