This article presents a design and development method of a DC-DC boost converter with constant output voltage. This system has a nonlinear dynamic behavior, as it works in switch-mode. Moreover, it is exposed to significant variations which may take this system away from nominal conditions, due to changes on the load or on the line voltage at the input. From a fluctuating or a variable input voltage, boost converter is able to step up the input voltage to a higher constant dc output voltage using the Non-linear feedback controllers such as PID controller and the Sliding Mode controllers. By this technique, the output of the converter is measured and compared with a reference voltage. The differential of the compared value will be used to produce a pulse width modulation signal to control switch in the boost converter. Simulation results describe the performance of the proposed design.
