有源Buck-Boost逆变器两种调制策略的对比分析

The inverter used in the new energy power generation system should have the ability to adapt a wide range of dc input voltage. Based on the active buck-boost inverter, which consists of a full bridge and boost ac/ac part, two modulation methods are compared: constant boost ratio modulation and dual-mode modulation. Along with the relationship of the input dc voltage and the reference ac voltage, t...
