High-Voltage Pulsed Power Supply to Generate Wide Pulses Combined With Narrow Pulses

This paper proposes a pulsed power supply topology based on the combination of capacitor-diode voltage multiplier and resonant circuit. It generates high output voltage pulses with low ac input voltage using power electronics switches. Based on the type of application, simple or combined mode pulses can be created by proposed topology. The combined mode pulse (wide pulses combined with narrow pulses) generation can be a very good alternative strategy for food sterilization, which can reduce the amount of consumed power and avoid side effects of wide pulses used in the food treatment process. Simulation and experimental results are presented to verify the proposed topology.
