Purification of Drinking Water by Application of High Voltage Electric Pulses Generated from Boost Converter and Voltage Multipliers

Abstract: Drinking water can be purified by application of electric pulses across the water sample that has to be treated. Application of high Pulsed Electric Field (PEF) to the water kills the germs and the bacteria present and thus purify it. In this paper, a high voltage electric pulse generator module is proposed, which consists of boost converter and a capacitor diode voltage multiplier (CDVM) with a closed loop control on its output voltage. A low voltage DC source is used at the input and the output of the module will be a pulsed output voltage. The proposed generator is validated by simulation study.
