| ABSTRACT : |
The use of soft-switching techniques, alleviates switching loss problems and allows a significant increase in the converter switching frequency. Small size and improved transient performance can be achieved through high switching frequency if resonant converter are adopted for these applications. Major advantages of this converter are leakage and magnetizing inductance of the high-frequency transformer that are used as a part of resonant circuit, and the output rectifier voltage is clamped to the output voltage. Converter operates in soft switching for the inverter switches with a narrow frequency control range and the tank current decreases with the load current. The switching process are softly commutated. Therefore the switching losses and noises are reduced. This makes this converter suitable for applications such as high performance electric drives, battery charges, with improved power factor. The current work is focused on simulation of Series Resonant Power Factor Correction AC - DC Converter using Matlab simulation.
