In a previous paper, I presented a new sinusoidal-wave output inverter, which is based on the principle of magnetic oscillation. An ac voltage source is connected to an excitation winding of the magnetic circuit in series. Current flows through the ac voltage source can be controlled by small signal-current flows through a control winding of the magnetic circuit, according to the law of equal ampere-turns. The inverter, therefore, can send electric power directly to the ac voltage source when the small signal-current is sinusoidal, and will be applicable to an electric power interconnection system. In this paper, I calculate the basic characteristics of the inverter in dc control to clarify the conditions for stable operation of the magnetic oscillation circuit by using SPICE. This paper describes the calculated results for the maximum output electric power of the inverter.
