Hello guys, i work on a boost converter with pic16f876A. anyway the pic works good with duty cycle variable by push butons(manualy). Now the source is without feedback. I read the output voltage in ADC and i want to make some modification:
-I want to set a output voltage from push butons and the Uc increase the duty cycle auto until the Vout=Vset. If Vout>Vset the uC need to decrease the duty cycle, if the Vset< Vout the uC increase pwm until Vset=Vout. Limits min 12v max 40v (Vout). I want to implementate a feedback. So who can help me?
