May I know how to calculate the value of C1, R1, and R2 in the below-shown circuit? The input voltage is 12 V.

    Have you tried to simulate the circuit? Do you understand the purpose of each element in the circuit? – winny Jul 31 '23 at 06:51
  • @winny May I Know which tool is suitable to simulate this Circuit? – Chitharanjan Jul 31 '23 at 06:59

    The two thing: The R1, R2 divider have to ensure enough voltage between G and S in steady state to mosfet fully open. And set the RC time constant according needs. Do not forget the Fet is in linear region during inrush (causes power stress of fet). – Michal Podmanický Jul 31 '23 at 07:05
  • Beware of mosfet spreads ,What if power is removed and Cin discharges well before C1 discharges then power is suddenly reapplied spiking Cin. – Autistic Jul 31 '23 at 07:20

    Falstad, LTspice are two popular ones. Do you understand the function of each component in the schematic? – winny Jul 31 '23 at 08:13
  • @winny can you please elaborate on the function of each component? – Chitharanjan Aug 01 '23 at 07:12
  • Let's start with what you know and we'll fill in you in from there. What does each component do? What happens when you lower or raise the value of each component. – winny Aug 01 '23 at 07:23
