Abstract
This paper presents the various control methods of DC-DC converter to maintain constant output voltage. Voltage mode control (VMC), Current mode control (CMC) and Sliding mode of control (SMC) schemes are to maintain the voltage at the load end for varying loading conditions and varying supply conditions. Results of VMC and CMC are compared with SMC method. Performance of SMC is better for changes in input voltage and load compared to the voltage-mode and current-mode control methods. SMC control method can well regulate the output voltage even in large range of load and line variation.
