Numerical Analysis of Fundamental Characteristics of Magnetic Oscillation DC-AC Power Converter

This paper describes the numerical analysis of fundamental characteristics of a magnetic oscillation direct current/alternating current (dc-ac) power converter that can supply electric power to an ac-voltage source such as a line electric power source. We present a simulation model of the magnetic oscillation circuit based on a general purpose circuit simulation program called “SPICE” to quantitatively analyze it. The simulation results of the fundamental characteristics agree well with those from experiments. A method of improving the characteristics to control the output electric power, which is based on the analytical results, is also described in this paper.
