I have designed a driver circuit using HCPL-3120.
i think i am getting the output pulses but i am not able to vary the voltage and the pulse width of the output pulses.
i am attaching the circuit dig., output voltage and input voltage...
if anyone has any idea please reply....
To vary pusle width at the output you will need to vary the pulse width at V7 source. Currently you have configured V7 to give you 50% duty cycle.
Duty Cycle = PW/PER * 100
and to vary output voltage you will need to adjust output voltages of V8 in your designed circuits.
