摘要：

Dual buck inverter is a new instrument which has the characteristics of high frequency and efficiency. How ever the output of the bridge is in bi-polarity PWM waveform and the voltage stress is high, just like half bridge inverter. To overcome those problems, three level combined switches are adopted to replace the parts of a dual buck inverter. Then we obtain some three-level dual buck inverter topologies which have uni-polarity PWM waveforms output, and voltage stress is low. A new three-level dual buck inverter, which has less switches due to the use of half load-cycle operation mode, is presented based on those topologies. The filter of the new inverter is reduced and the merits of high efficiency and high reliable is remain at the same time. Provided experiment verifies those analysis.
