要約(英語): Electric vehicles are equipped with an isolated DC-DC converter for controlling the bidirectional DC power flow. In this case, a current sensor was installed inside the circuit. This paper proposes a current sensor using current transformers for bidirectional DC-DC converters. The current sensor comprises a current transformer (CT), diode rectifier, and MOSFET. The current sensor can detect a pulse current containing a DC component without any magnetic saturation. This paper shows a circuit configuration of the bidirectional current sensor, and the principle of the bidirectional current detection of the sensor is analyzed. The validity of this analysis is verified through an experiment with the DC-DC converter rated at 150V and 1.4kW.
