Efficiency Analysis and Comparative Study of Hard and Soft Switching DC-DC Converters in a Wind Farm
This paper focuses on efficiency analysis and comparative study of hard-and soft-switching dc-dc boost converters in wind farms. The efficiency of an ac or a dc-based wind farm is dependent on the efficiency of its key components such as dc-dc converters. The demand for dc-dc converters depends on how voltage fluctuations are adjusted. This paper analyzes the efficiency of the switching method used in dc-dc converters. The switching and conduction losses of all the components of the dc-dc converters are modeled and the efficiency is calculated accurately. The power rating vs. efficiency of the dc-dc converters is also considered. The efficiency of the converter in soft switching mode is greater than in hard switching mode. The efficient operation of the converter at a given power rating is shown graphically.
