Hi, I need a current source circuit using PWM technique. I need to vary the current from 0 to 1A by varying pulse width of 100HZ frequency signal. Please reply...
hi as you have not given much details i assume its dc current you want to control.
The easiest method that comes to my mind is a simple V to I converter with the pwm waveform(filtered) as input.
Also are sure the frequency is 100Hz? Normally PWM converters etc use frequency around 10-20 kHz. which makes filtering the pwm is much easier.
