Factors affecting the reliability of CPDs include power factor, switching frequency, thermal impedance, and traction load. Of these, switching frequency exerts a significant effect and can be controlled most conveniently. Therefore, this section discusses methods to enhance the reliability of CPDs by focusing on switching frequency as the control variable, based on the physical failure mechanisms of IGBT modules, to formulate an optimal frequency conversion control strategy.
