Abstract-An innovative ultrahigh step-up dc-dc converter that integrates a dual-stage boost converter, a coupled inductor, and a multiplier cell. The dual-stage boost converter provides an initial voltage boost, while the coupled inductor enables efficient energy transfer and recycling of leakage energy. The multiplier cell further amplifies the output voltage. This configuration reduces voltage stress on power switches, decreases the size of passive components, and ensures continuous input current. With these features, the proposed converter offers enhanced performance, making it suitable for applications requiring high voltage conversion with minimal power losses. The simulation prototype steps up the input voltage using a 150-W prototype converter from 25 V to 550 V using MATLAB.
