In a previous paper, we presented a dc power-measuring circuit based on magnetic oscillation. The dc voltage to be measured is connected to the excitation winding of the magnetic oscillation circuit in a dc power-measuring circuit. In this paper, we propose a new sine-wave inverter utilizing the magnetic oscillation circuit, which is based on the same principle. Current flow through the excitation winding can be controlled by small signal-current flows through the control winding, according to the law of equal ampere-turns. The inverter is connected to a commercial-frequency voltage source and can send electric power directly to the voltage source. This paper describes operating principles and the fundamental characteristics of the inverter.
