Title:
インバータ装置及びそれに用いられる半導体装置。
Document Type and Number:
Japanese Patent JP4913661
Kind Code:
B2
Abstract:
An inverter apparatus is for correcting deviations among current detectors of a three-phase motor. The inverter apparatus includes bidirectional switching elements that have on and off states in the cases in which there are 1 and 0 mean on- and off-states. The states are alternately repeated by controlling the switches, and measurement for correcting the deviations among the current detectors are obtained in the state Currents have the same amplitude flow on a U phase and a V phase. In the state of normal use, the inverter apparatus is operated by correcting detected current values based on the measurement data.
