Renewable sources are developing fast and widely used to reduce the non-renewable sources. In this paper, a standalone, portable, green energy dependent, dual input SEPIC converter is developed with a 12 V DC output voltage The control strategy for this converter is designed to retain output voltage within 12 V when inputs source is in the wide range of 6V to 24V. Sharing only the output capacitor method is one of the multi-input method and has been used to combine two input energy which are solar and vibration in this research. This system contains feedback system and is designed by using Proportional Integral Derivative (PID) controller to ensure the output voltage is 12V. The converter with the controller has no overshoot, it settling time is about 0.02 second and the rise time is about 0.0001 second. Thus, it is proved the converter with controller is capable to reduce the settling time and rise time compare to converter without controller.
