Abstract
An ultrasonic power generator for operation at a one and a half kilowatt power output from a 220 volt, 50 hertz AC line comprising a transducer coil impedance associated with a resonant capacitor, said generator being generally designed for a one kilowatt power output from a 110 volt, 60 hertz AC line. The generator circuit includes at least one thyristor for switching the resonant capacitor terminals and an oscillating circuit having a time basis including said capacitor designed for circulating a high frequency current at the desired ultrasonic operating frequency sufficient to generate one and a half ohmic kilowatts. A small high Q inductance is added to the inductive reactance of said transducer coil for adjustment to the capacitance values of the oscillating circuit.
