This article presents the new hybrid switched-capacitor-based transformerless DC-DC converters with a high step-up capability and common ground features. The proposed converter provides low voltage stress across semiconductor devices to utilize MOSFETs with lower Rdson and low voltage ratings. In addition, the diodes in switched-capacitor cells with low voltage stress can reduce the reverse recovery power loss of the converter. Thus, the overall efficiency of the proposed converter can be increased. The converter circuit, operating principle, and design guideline of the proposed converter are discussed. To confirm the performance of the proposed converter, a detailed comparison study with the conventional hybrid switched-capacitor converter is also presented. Finally, a laboratory prototype with 200 W, 25 V to 200 V is set up to correct the effectiveness of the proposed converter
