In the closed loop topology for a coupled inductor based DC-DC converter we have a tendency to introduce a voltage multiplier converter with coupled inductance for high gain output charging the battery of a feedback loop for DC machine drive for variable input voltage. The dual switches structure is helpful to scale back the voltage stress and current stress of the switch. Additionally, 2 multiplier capacitors are charged throughout the switch-on period and switch-off period, which will

... the voltage conversion gain. Meanwhile, the energy stored within the inductance is recycled with the clamped capacitors. Thus, 2 main power switches with low on-resistance and low current stress are available. This project illustrates the operation principle of the designed DC-DC converter, the output voltage of the high step-up converter is maintained constant by automatic variation of the duty ratio with feedback as PI Controller. The constant output voltage for varying input DC voltage is represented graphically using MATLAB simulation for various industrial applications.
