Control Characteristics of the Output Electric Power of a Magnetic Oscillation DC-AC Converter Using a Bridge-Connected Magnetic Circuit

This paper describes the fundamental characteristics of a magnetic oscillation dc-ac power converter using a magnetic control device called a bridge-connected magnetic circuit. An ac-voltage source such as a line electric power source is connected in series to an excitation winding of the magnetic oscillation circuit. The converter can supply electric power to the ac-voltage source, and can control its output electric power by means of a small dc current that flows through a winding of a U-form core that composes the bridge-connected magnetic circuit. The characteristics of the converter in controlling the output electric power are described in this paper.
