摘要：The objective is to develop a fault diagnose scheme for MOSFET’s open switch faults for PWM voltage source inverter (PWM-VSI) motor drives. Here system monitors line to line voltage as well as switching signals nevertheless the triggering time of MOSFET, under both healthy and faulty conditions. So the measurement of line to line voltage is taken which gives the information about switching states. This can be achieved by a designing simple hardware and can be implemented in the existing motor drive system. The system not only detects the single and multiple faults diagnosis but also minimizes the time taken for fault recognition
