Abstract

An ultra high gain quadratic boost converter based on switched-capacitor is proposed in this article. The ultra high gain is achieved with a low duty ratio and a wide range of flexibility. The proposed converter provides significantly reduced device voltage stress and source current ripple. This article presents in detail discussion on the operating principle, continuous conduction mode (CCM) and, discontinuous conduction modes (DCM) and the parasitics effect on the output voltage and efficiency of the proposed converter. Also, the stated converter performance comparison with similar quadratic boost dc-dc converters is presented. The performance indices of the proposed converter are verified by a prototype of 400 V, 50 kHz, 200 W, subsequently, the converter is also experimented for 800 V output with suitable elements to verify its performance feasibility for ultra voltage gain.
