Hai friends,
In my project I have to control speed of AC230V,50HZ,4A,single phase motor.I tried TRIAC BT136 with optocoupler 3041 but it switching on when the PWM is high but in low pulse its not working.....Then removed the optocoupler it working fine.
Then used IRF540 but it always in ON condition.Its not responsible with PWM.
Please provide suggestion to control the motor speed by using PWM controls
