ABSTRACT

Conventional power transformer adopted AC/DC and DC/AC converters in order to transform an AC voltage signal to another AC voltage signal. Recently, a few studies have been done on the direct conversion of an AC voltage to another AC voltage. In this paper, we present a digital controller system which can be applied to intelligent AC to AC voltage conversion to be used for an automatic voltage control by using only few transistors, replacing conventional electrical power transformers with solid state switches. We have designed an AC to AC voltage converter by adopting solid state switches in order to obtain an AC output power. It was possible to obtain highly efficient AC to AC converter by adopting AC power switches for pulse-width modulator(PWM). By introducing only few solid-state switches, high power solid state devices and networks of power distribution. The P-spice simulation showed the effective output of our converter we designed.
