| Abstract |
A modular configuration of extended-period quasi-resonant power converters is developed. In this paper, the described converters offer advantageous features such as high power factor, effective in reducing EMI emission, improving overall efficiency, direct output coupling and automatic power factor correction. Also, the zero switching technique is applied to achieve the zero turn on and turn off losses. The operating principles are confined with the computer simulation and the experiment. The results of the converter were analysis and tested to verify the theory. |
