I have connected a 1k resistor between the MOS Gate and the optocoupler and another 1k resistor between the PIC and optocoupler.I believe that the 1K resistor is a bit to high.
The system is basically a voltage copier ,the circuits above subtracts the input voltages while the circuit above adds the input voltages .Yes the voltage regulators have caps connected .Yes the optocouplers does support PWM .When i measured using a CRO i did measure the pulses .The circuit...
Yes,i does have a CCP module ...but i am unable to obtain the desired output from that with the correct delay .I am attaching the schematic ..i basically want to drive the alternative mosfets with a delay of 10 micro seconds :)
When i measured the voltage across the pin 4 and pin 5 of the MCt2e driver it indicated 12 volts.Wouldn't that confirm that the MOS are triggered correctly using the optocoupler ? is there anything wrong with the 1k resistor in series with the MOS Gate ?
Hey,
I wanted to trigger mosfets using PWM from PIC 16F877A .The PWM is supposed to oscillate at 50Khz with the duty cycle of about 50 %.I want to draw four PWM signals from the PIC MCU that are apart from each other by 10 micro seconds.But i am unable to achieve the required duty cycle...
Hey,
I am trying to implement a DC-DC converter and there seems to be a problem with the circuit. Bascially,i checked the PWM from PIC and it seems to be fine.However i was wondering if it was normal to connect the 1k resistors with the optocoupler.I was browsing when i noticed the most of you...
