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

摘要

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