Claims

[Scope of utility model registration request]

In a converter device that is connected to another converter device via a reverse current blocking diode and that performs redundant operation by controlling the voltage tracking circuit and constant voltage control circuit by remote sensing, one end of the first phase compensation capacitor is connected to the converter device. The other end is connected to the positive output terminal of the converter, and the other end is connected to the positive remote sensing terminal using a part of the voltage dividing resistor for detecting the load voltage of the constant voltage control circuit, and the negative output terminal and remote sensing A converter device characterized in that a second phase compensation capacitor is connected between the ends to prevent hunting due to a phase lag in a load voltage caused by remote sensing.
