Abstract  

Cascade H-bridge inverter has been widely used in various applications, especially where separate DC sources naturally exist in the places, such as Photovoltaic, fuel cells, battery energy storage, and electric vehicle drives. The proposed cascade dual buck inverter with phase-shift MANAGEMENT inherits all the merits of dual buck type inverters and overcomes some of their drawbacks. Compare to traditional cascade inverters, it has much enhanced system reliability thanks to no shoot-through problems and lower switching loss with the help of using power MOSFETs.With phase-shift MANAGEMENT, it theoretically eliminates the inherent current zero-crossing distortion of the single-unit dual buck type inverter. In addition, phase-shift MANAGEMENT and cascade topology can greatly reduce the ripple current or cut down the size of passive components by increasing the equivalent switching frequency.
