Abstract
A converter includes a converter circuit that converts the AC voltages supplied from the Δ-connection and the Y-connection, which are two systems of a 12-phase rectifier transformer, to a DC voltage; a current detector that detects the current in a DC bus output from the converter circuit; and an imbalance detection unit that detects the occurrence of an imbalance between the current output from the Δ-connection and the current output from the Y-connection, the currents being detected by the current detector. The converter can detect an imbalance that occurs between the current flowing in the diode bridge on the Δ-connection side and the current flowing in the diode bridge on the Y-connection side.
