Abstract
A novel inverter used special switch logic circuit to realize series or parallel output was proposed in this paper.Half load cycle operating mode of the inverter was presented,and two control schemes—synchronous switch PWM (SSPWM) and interleaving switch PWM (ISPWM)—were analyzed here.The proposed inverter has the characteristics of concise circuit configuration,no shoot-through problem,and high frequency and efficiency operation.Dual different standard AC outputs can get by series output or parallel output,and there is no freewheeling current in the circuit.Finally,the fulfilled 1000W prototype of the inverter with high efficiency confirms the design and performance.
