Abstract

The pulsed power system is widely available for use in pulse generator applications. Generally, the pulse generator is required for very short pulse width and high peak value. We have designed and fabricated our own pulsed type power system and through its use, we investigated microbe removal characteristics. This paper introduces a simple pulsed power system for removing various microbes caused by dirty water. This system includes a 2 times power supply circuit, IR2110 operated by using a fixed voltage regulator 7812 and 7805, and the switching MOSFET (Metal Oxide Semiconductor Field Effect Transistor). We can also control this process by using a PIC one chip microprocessor. As a result, we can obtain good removing characteristics of various microbes by adjusting the charging voltage, the pulse repetition rate and the electrical field inducing time.
