Abstract:
This project proposes a zero voltage switching technique based combination of MOSFET inverter and IGBT converter fed PMDC drive. The proposed converter topology reduces voltage stress and conduction losses using zero voltage switching technique and also performs speed control of PMDC motor using PI controller. Proposed converter provides very efficient power conversion due to low voltage stress, less switching losses and requirements of power devices less. The proposed converter topology permits all switching devices to operate under zero voltage switching technique. Moreover, the voltage stress of the primary switches is reduced by using voltage divider which makes the low-voltage rated power devices available to improve the circuit performance and speed control of PMDC Motor using PI controller.
