Abstract

Switched reluctance motor system is a novel electromagnetic system with good application prospects. The loss from the power converter is one of the main issues for the design and operation of the system. In this paper, the methods to calculate the power loss of the power converter in switched reluctance motor drive are introduced. The simulation model for the whole system is built, which can calculate the power loss of every power MOSFET. Then the influences of the parameters, such as PWM duty cycle, frequency, motor speed, and turn off angle, on the device power loss are analyzed. At last, the device junction temperature is presented.
