SiC+Si混合型三电平ANPC逆变器损耗均衡调制策略
Modulation Scheme of SiC+Si Hybrid Three-Level ANPC Inverter with Loss-Balancing Distribution
摘要
Abstract
To address the problems of uneven switching loss and low efficiency existing in the three-level active neutral point clamped(3L-ANPC)inverter,a hybrid 3L-ANPC inverter composed of 4 SiC power devices and 2 Si power devices has been built,and two modulation schemes have been proposed to balance the distribution of switching loss.The proposed modu-lation schemes complement each other and are mixed use in a cycle.By the regulation of the proportion time in a cycle for the two modulation schemes,the balanced distribution of loss and temperature for the power devices in 3L-ANPC inverter has been realized.A 3 kW experimental platform has been constructed,the device temperature and working efficiency have been compared for 3L-ANPC inverter modulated by the proposed scheme of loss-balancing distribution and a traditional modula-tion scheme,the result has shown that the working efficiency has been improved by 0.5%,and the maximum device tempera-ture difference has been reduced by 78.6%.关键词
