一种具有双工作模式的负输出高二次变换比DC-DC变换器

A negative-output high quadratic conversion ratio dc-dc converter with dual working modes is proposed. One working mode is a step-up mode, and the other is a step-up/step-down mode. Analysis of the circuit principle and different operation modes, steady-state calculation, and small-signal modeling are presented. Comparisons of the proposed converter with other converters demonstrate that the propo...
