ABSTRACT:
A high-frequency power supply which is primarily intended for use with an inductive heating apparatus. The high-frequency power supply has a pre-regulator for emitting a constant output voltage, an inverter for generating a constant output voltage, and an output network for amplifying the constant output voltage and converting the constant output voltage to a high-frequency constant output current. The power supply disclosed generates a very high frequency ac output, drives a wide range of possible loads, minimizes root mean square input current for a given output power, and can be powered from a wide range of input power sources.
