非对称PWM串联电容高变比DC-DC变换器

In this letter, an asymmetrical pulsewidth modulated (PWM) scheme is proposed to solve the inductor current unbalance and nonlinear voltage gain issues of the series-capacitor (SC) high-conversion-ratio (HCR) converter when $D > 0.5$. With the proposed scheme, the converter can achieve both current balancing and high step-down conversion even for $D > 0.5$. As a result, combined with the conventio...
