Abstract

The SCR AC voltage controller controls the magnitude of the output voltage by controlling the delay angle based on the zero-crossing points of the input AC voltage. This paper presents a method to generate digitally SCR gate signal by using AVR in order to minimize the effects of ripples or noises including AC input voltage. The validity of the proposed SCR gate signal generation technique is verified through experiment result.
