Abstract
A VHF inverter including an inverter circuit (100) for providing an inverter output; a constant magnitude, variable phase impedance transforming circuit (54, 154) responsive the inverter; and a load circuit (55, 155) responsive to the impedance transforming circuit.
Claims3
A VHF DC to AC inverter for providing power to a load circuit, the VHF DC to AC inverter comprising:
- switching inverter means connected between first and second voltages for providing an inverter output;
- and
- impedance transforming means connected between the switching inverter means and the load circuit, said impedance transforming means configured to present an input impedance having a magnitude that is substantially constant with variations of the load circuit, and a phase angle that varies with variations of the load circuit, said impedance transferring means comprising:
- (i) a series capacitor connected between an output of the switching inverter means and an input of said load circuit,
- (ii) a first shunt inductor connected between a first terminal of said capacitor and a reference potential, and
- (iii) a second shunt inductor connected between a second terminal of said capacitor and the reference potential.
