一种六开关七电平三倍升压逆变器

Multilevel inverters in renewable applications usually require a high-voltage dc link fed by a front-end dc--dc boost stage. Such a two-stage power conversion, however, increases the switch count, leading to higher costs and power losses. To lower the number of switches, this letter proposes a six-switch inverter, capable of generating a seven-level voltage and a triple-voltage boost. Both feature...
