As the aircraft industry is moving towards the all electric and More Electric Aircraft (MEA), there is increase demand for electrical power in the aircraft. The trend in the aircraft industry is to replace hydraulic and pneumatic systems with electrical systems achieving more comfort and monitoring features. Moreover, the structure of MEA distribution system improves aircraft maintainability, r...

The main concern about the bi-directional AC-DC converter is to maintain utility power factor near to unity. One Cycle Controller (OCC) is one of the outstanding control techniques to control these power electronic converters. One Cycle Controller comprises one integrator with reset along with a few linear components like analog comparators, flip-flops, and a clock. This paper presents a hardwa...

This paper discusses the basic family of three-level (TL) dc–dc converters. The origin of TL converters and their basic topological variations are described. Systematic procedures leading to improved and simplified circuit topologies are discussed. A feedforward control scheme that ensures the proper functioning of these converters is proposed. Moreover, the virtues and drawbacks of these conve...

The reliability of power electronic converters is a major concern in industrial applications because using prone-to-failure elements such as high-power semiconductor devices and capacitors. Hence, designing fault-tolerant inverters has been great interest among researchers both academia industry over the last decade. Among three stages fault management, compensating most important challenging p...

The auxiliary resonant commutated pole (ARCP) converter is currently of intense interest for use in a variety of power electronic converters, and is one of the cornerstones of the Navy's Power Electronic Building Block (PEBB) effort. In this paper a detailed discussion of the required switching times needed to achieve completely soft switching operation with only one current sensor per phase is...

This chapter introduces the operation and control of a Doubly-fed Induction Generator (DFIG) system. The DFIG is currently the system of choice for multi-MW wind turbines. The aerodynamic system must be capable of operating over a wide wind speed range in order to achieve optimum aerodynamic efficiency by tracking the optimum tip-speed ratio. Therefore, the generator’s rotor must be able to ope...
