Title:
【発明の名称】電力変換器の制御装置
Document Type and Number:
Japanese Patent JP2889133
Kind Code:
B2
Abstract:
A power converter controlling apparatus operates voltage signals different in phase from phases of commutation voltages of each switching device by 90 degrees to transform the voltage signals and the commutation voltages in conformity with polar coordinate transformation, and operates amplitudes of the commutation voltages and the phase differences of the commutation voltages to a reference phase on the results of the transformation to operate phase-control angles of each switching device on the amplitudes and the phase differences.
