Abstract

In this paper, a novel voltage-boosting converter is presented, which combines one charge pump and one coupled inductor. The corresponding voltage gain is greater than that of the existing step-up converter combing KY and buck-boost converters. Since the proposed converter possesses one output inductor, the output current is non-pulsating. As a result, both the output current ripple and the output voltage ripple can be reduced significantly. After some mathematical deductions, an experimental setup with 12V input voltage, 72V output voltage, and 60W output power is used to verify the effectiveness of the proposed converter.
