This paper first presents open loop behavior of buck boost and cuk dc-dc converter operated under Continuous conduction mode (CCM). This is achieved withthe help of state equations and MATLAB/SIMULINK tool for simulation of those state equations. Using the knowledge of open loop converter behavior, a closed loop converter is designed. DC-DC converter will be designed for specific line and load conditions. But in practice there is deviation of the circuit operation from the desired nominal behavior due to changes in the source, load and circuit parameters. So we need to design a proper controller or compensator to overcome this situation of the circuit operation. This paper presents PID controller designed such that any input variations produces a constant output voltage.
