    i have doing my final year project with title on load tap changer transformer. my project is using single phase power supply with 230V 60hZ ( for malayasia ) for my project, i set my load voltage reference as 100VAC with tolerance +-5% deviataion. so if the voltage out of this reference voltage, the microcontroller will send a signal to triac circuit to select a suitable tapping. to test my circuit, i need to change ( increase or decrease ) the input voltage 230V of my tapping transformer so that the tapping will change according to the value of the input voltage. how can i control this input voltage for my tapping transformer so that it can up and down? thank you very much.
