摘　　要：高频电流纹波影响了变换器电感体积和质量,针对准开关升压逆变器,传统的直通调制算法并不能做到电感电流纹波最小。该文提出一种最小电感电流纹波的空间矢量调制方法,重新分配了开关管导通与关断时序。在此基础上,推导使得电感电流纹波最小时直通占空比和导通占空比所满足的数学关系。最后,通过仿真和实验对比了所提出的新型调制算法和传统算法在抑制电感电流纹波方面的性能,结果证明了理论分析的正确性。The high frequency current ripple affects the volume and weight of the converter inductor.For the quasi-switched-Boost inverter,the traditional shoot-through modulation algorithm cannot minimize the inductor current ripple.A space vector modulation method with the minimum inductor current ripple was proposed to redistribute the turn-on and turn-off sequences of the switches.On this basis,the mathematical relationship between the shoot-through ratio and the conduction duty ratio was derived.Finally,the performance of the proposed modulation algorithm and the traditional algorithm in suppressing the inductor current ripple was compared by simulations and experiments.The results can agree with the theoretical analysis.
