摘　　要：将开关-耦合电感单元引入二次型变换器,采用一个耦合电感和两个独立电感,在开关管关断时,电感为电容充电;导通时,利用电容为负载供电。与传统变换器相比,所提出的变换器采用更少的器件,能得到高电压增益效果与低占空比。采用了降低电压应力的电容,二极管和半导体开关,开关管应力更低。提出了稳态和比较性能分析,制作了一台140W实验平台,给出实验数据与结论,验证了理论分析的正确性。The switch coupled-inductor unit is introduced into the quadratic converter,and one coupled-inductor and two independent inductors are used.When the switch is turned off,the inductor charges the capacitor;When conducting,use capacitors to power the load.Compared with traditional converters,the proposed converter uses fewer devices meanwhile can achieve high voltage gain effect and low duty cycle.The use of capacitors,diodes,and semiconductor switches with reduced voltage stress results in lower stress on the switch tube.A steady-state and comparative performance analysis is proposed,developed a 140 W experimental platform,provided experimental data and conclusions,and verified the correctness of the theoretical analysis.
