This paper presents a coupled inductor dual-buck full-bridge inverter (CI DBFBI) to solve the shoot-through problem of the conventional inverter and increase the input-voltage utilization rate of the dual-buck half-bridge inverter (DBHBI). Hysteresis current control is used in the CI DBFBI. All switches and diodes operate at each half line cycle, and the freewheeling current flows through the independent...
Parallel operation of inverters improves the reliability, maintainability, expandability, and standardization. Many control methods have been proposed. The master- slave method can not realize the redundancy because the slave modules are dependent on the master module, the wireless control method using frequency and voltage droop technique presents too poor output characteristics. Distributed control...
Dual buck inverter is a high reliable inverter due to no shoot-through problem. This paper successfully applies charge control to dual buck inverter. It can achieve half cycle modulation which greatly decreases switching loss. Comparing with hysteresis control, the inverter operates in fixed frequency and is immune to switching noise. Parameters design of the inverter is given and is verified by the...
