Abstract
The authors propose a main circuit and a control method of a high-frequency link DC/AC power converter with three-phase output using a cycloconverter which converts a high-frequency voltage into a three-phase commercial frequency voltage. This DC/AC converter can control the flow of power bidirectionally, and can charge a DC power supply and compensate for instantaneous reactive power. Simulations and experiments were carried out to confirm the feasibility of the proposed method
