SEPIC Converter Proteus Simulation

  1. Hi Sir.

    I wanted to know if you could post a video on the closed loop circuit for a SEPIC converter perhaps using Proteus or MATLAB. I’m getting confused as to how to go about simulating a SEPIC closed loop with PI controller.

    your positive response would be highly appreciated.

    • Make a voltage divider to sense the output voltage. Make sure, the voltage sensor value never crosses 5V.
      Give it back to the microcontroller and keep tracking it using the analogRead() function in arduino. Give an if..else logic to change the PWM output (analogWrite() function in arduino) based on the sensed output voltage value. For example, if the sensed voltage is lesser…increase the duty cycle and vice-versa.

      In this way, you will have a constant output voltage no matter what your load is.
      Hope it helps.

  2. Good morning could you help me with the formulas to obtain the coils and capacitors in your example please, or any link where you have been based to calculate the values โ€‹โ€‹of the capacitors and coils, please feel free to be as detailed as possible I am starting and I need a lot of help
