n电平DC-DC-AC逆变器的嵌入式控制

A generalized multilevel inverter (MLI) with front-end dc–dc conversion stage followed by a synchronized H-bridge is presented. By using this configuration along with the proposed embedded control, any desired number of levels (n) in the output voltage can be produced. The dc–dc conversion stage employs an asynchronous buck converter. The duty cycle of dc–dc converter is varied in the form of m-le...
