High Voltage Transformer design based on Flyback Switching Power Supply

Abstract

The single source generator could change the frequency and duty cycle of the pulse to control the voltage of output in flyback switching power supply. A variety of methods and calculations could be used to design high voltage transformer, such as AP method that will be used in this transformer, kg method and KRP method. In this paper, the process of how to select the magnetic core and the other parameters of the transformer will be discussed step by step. At first, the voltage of output will be over two thousand and five hundred voltage. The single source generator changing the frequency and duty cycle, the voltage of output will stay stability on five hundred voltage. The seize of the transformer is smaller than that has been used, so it will be beneficial for the circuit integrated.
