ABSTRACT
Induction heating (IH) power supplies are frequency changers that convert power at the available utility line frequency to single-phase power at a frequency appropriate for the particular IH application. They are often referred to as converters, inverters, or oscillators, but they are generally a combination of these. The converter portion of the power supply converts the line frequency alternating current (AC) input to direct current (DC), and the inverter or oscillator portion changes the DC to single-phase AC at the required heating frequency.
