High Voltage Flyback Converter for Pulsed Loaded Applications

High voltage pulses of the output power ranging from 5 W to 200 W are employed in food processing systems, water treatment process, electroporation, industrial and medical applications etc. The power converter configuration implemented to generate high voltage pulses is selected depending on the peak power rating requirement. In this work, a flyback converter configuration is selected to charge the energy storage capacitor meeting the desired voltage magnitude and charging time constraint. The energy storage capacitor is charged following peak current mode control with boundary conduction mode. In this proposed work, high voltage rectangular pulses of 1000 V magnitude with the desired pulse repetitive rate and pulse width is designed for various case studies and validated through corresponding simulation results.
