A novel high‐voltage‐boosting converter is presented herein, which combines the traditional buck–boost converter, the charge pump capacitor and the coupling inductor. By doing so, the proposed converter possesses a high‐voltage conversion ratio, which can be obtained based on not only the duty cycle, but also the turn ratio so as to increase design feasibility. Above all, the used switch is driven without isolation and hence the gate driving circuit is relatively simple, thereby upgrading the industrial application capability of this converter. In this study, the basic operating principles and the associated mathematical deductions are firstly described in detail, and finally some experimental results are provided to demonstrate the effectiveness of the proposed high‐voltage‐boosting converter.
