Hi,
I have 12 0 12V transformer of 30A max transformer of UPS which has 4-5 tapping at output for AVR (external) and the circuit is working fine i have tested 200Watt BULB and 300Watt Drill machine running.
the amp meter was showing more than ~15A at heavy load from 12V 7AH battery of UPS. so i guess the output power tested till now is 24Vx15A =360VA.
The no-load current taken by Transformer is 900mA. as there is no voltage regulation circuit so voltage fall down at load.
Someone suggest me to use 3524 PWM modulator. please help me with it as data sheet suggest the working freq range from 10hz to 400khz but in India 50hz is working freq., so, what to do??
