要約(英語): This paper proposes a coupled-inductor circuit that suppresses cross currents flowing through modular paralleled power converters. The proposed circuit consists of coupled transformers, a current sensor, and amplifiers. The circuit operates as coupling inductors when cross current flows through the converters, such that the volume of the inductors can be considerably minimized. In addition, the circuit can be used as a current sensor. The frequency bandwidth of the sensor can be further improved by adding a few components. The experimental results show characteristics of cross current suppression and current detection, and the propriety and effectiveness of the proposed circuit are confirmed.
