Abstract

A novel split phase dual buck inverter is researched. The inverter has the characteristics of concise main circuit configuration, freedom from shoot-through problems, and high-frequency high-efficiency operation. Reasonable control scheme is used to realize the inverter output in series or in parallel connection, so the inverter can offer dual different standard AC outputs to satisfy electricity appliance needs of different countries or regions. Synchronous-switch PWM (SSPVVM) control scheme and interleaving-switch PWM (ISPWM) control scheme are proposed here. The control schemes realize nonbiased current operation mode of the inverter, so there is no freewheeling current that exist in the traditional SPWM controlled dual buck inverter and power losses are dramatically reduced. A prototype has been developed and experimental results have been presented
