great video. Can you also do a video for current mode control of flyback and forward converter with soft start . Either in Qspice or LTSpice

[@MarcosAlonsoElectronics]

Thank you for your comment and suggestion

Good afternoon Professor Alonso. I have a question on Rs and Cs. Are these used for the soft start?

[@MarcosAlonsoElectronics]

Hi, thanks for your question. Rs and Cs are not for soft start. They are used to implement the power supply of the integrated circuit. Cs is a decoupling capacitor used to provide additional filtering at the input of the integrated circuit. Rs is used to bias the zener diode.

@@MarcosAlonsoElectronics Thank you so much Professor Alonso. I really appreciate it. My next question will be: how to implement the soft start in real application on such converter. On again, thank you so much for the knowledge you are sharing.
