Abstract :
An Impulse power supply has been designed simulates and tested in order to feed the primary of a high- frequency transformer. The Impulse power supply is based on a series load resonant topology and uses IGTBs as switching devices. The power converter can achieve zero switching with the aid of high frequency transformer. The device is capable of charging a 0.1 muF capacitor up to 5 kV in which accounts for a charging power of 5 kj/s. The novel control algorithm is achieved using fuzzy logic, which eminently considers the non linear control characteristics of Impulse power supply. The required charging voltage, together with the constraint of the charging time, translates into a required maximum power of 10 kW reduced in this initial version to 5 kW. The difficulty to control reliably such a power at the high-voltage side practically forbids any approach featuring a more or less stabilized DC high-voltage to be generated from a conventional 50 Hz transformer through rectification. Instead, it is more attractive to utilize a fuzzy logic control on high-frequency converter performing the regulation at the low-voltage side of its step-up transformer and charging the primary capacitor with high voltage pulses.
