Abstract

This paper describes basic characteristics of a direct current/alternating current (dc-ac) converter utilizing magnetic oscillation. The converter is constructed with power MOSFETs and a non-linear magnetic core. An ac-voltage source such as a line electric power source is connected in series to an excitation winding of the magnetic circuit. The converter can supply electric power to the ac-voltage source, and its electric power can be controlled by a small signal-current that flows through a control winding. The waveform of output current of the converter is almost sinusoidal. The output electric power of the converter increases by adding fast recovery diodes outside of the MOSFETs to cancel, and to replace, the body-diode of the MOSFETs.
