Abstract

A comparative study has been made for open loop, set point controlled microcontroller based buck converter with Si and SiC diode. The simulation and hardware results indicate that both in charging mode as well as in discharging mode SiC has a better performance compared to that with Si diode. Hardware results show that settling time and peak overshoot reduced to a great extent when SiC (CSD04060) is used in place of Si (MUR860) diode. There is a little improvement in form factor of the output voltage. This is because of very low or negligible value of reverse recovery current flowing through SiC diode. Due to the reduction in the switching losses in case of SiC (CSD04060) diode as compared to Si (MUR860) diode, the overall efficiency of buck converter is increased by about 5 percent.
