Title:
インバータシステムにおける電力ケーブルの分離検出方法
Document Type and Number:
Japanese Patent JP5731571
Kind Code:
B2
Abstract:
Disclosed is a method of detecting the disconnection state of a power cable in an inverter system. The method includes detecting a disconnection state of a first power cable by using a difference value between a battery voltage and a DC-link voltage, detecting a disconnection state of a second power cable by using a driving speed, a phase current instruction value, and an actual phase current value of a motor, and stopping driving of the motor if one of the first and second power cables is detected as being disconnected.
