Phase sequence alert
« on: June 12, 2019, 01:41:30 pm »
Three phase line was directly given to resistor - Diode network and I obtained a pulsed output of 10v DC . 3 number of 10v pulse will have a delay between each other since we are dealing with three phase supply . When RYB was applied the Led was always turned on . Where as if its RBY , led would blink . What exactly these 4 NAND gates are doing with these 3 pulses to create this output . Please help . I'm a newbie . I know what's NAND gate , but cant figure out how these pulses do the action ?

Why do you open a new thread when you already had one going?
