Abstract:
For motor drive applications, various protection functions are necessary to enable safe operation of all motor drive systems under the conditions of the short circuit, over current, and over temperature. This paper presents protective methods under the specific transient states such as abnormal operation of micro controller, disconnection of 15V power supply and short circuit between adjacent pins of Intelligent Power Module (IPM). They effectively contribute to the enhancement of system reliability in low power motor drives. In this paper, the specific transient states are described and remedial methods are provided with actual experimental results.
