Soft Switching with Cascaded Transformers to Drive the PMDC Motor
English
2015
International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering
English
This paper presents a soft switching technique used along with the series connected transformer to run a PMDC motor. The three level PWM circuits with two active switches and the capacitors are connected in parallel with it. The two switches are reduced in the existing method. Instead of those two switches two capacitors are used to reduce the switching losses. The series resonant converter is used to achieve ZVS turn-on for all power switches and zerocurrent switching for all rectifier diodes.
