Design of Multilevel Convertor for Wind Energy Applications

Multi level voltage source converters happen to be emerging as a fresh and an innovative variety of power converter alternatives for high-power applications. The multilevel voltage source conversion programs commonly Synthesize the set of stairs of voltage wave from a number of degrees of dc capacitor concentration. One of the primary limitations of the multi-level converters is the volt quality unbalance between different amounts. The methods to balance the voltage between different amounts normally involve voltage clamping or capacitor charge control. There are several methods of implementing voltage balance in multilevel converters. Without taking into consideration the standard magnetic coupled conversion programs, this paper presents recently developed multilevel ac electricity source converters Cascaded-inverters with separate power sources.The operating basic principle, features, constraints, and potential applications of this conversion program will be discussed.
