I designed my first SMPS this morning but I have 3 questions. The first 2 deal with if there is an equation to find the right value of capacitor and inductor to give a smooth DC signal into the load.
The 3rd question is I want to limit the current to 1 amp. My thought was if the gain of the transistors was 50 (arbitrary number) and I have 20 milliAmps flowing into the base I would assume that would set a cap of 1 amp. But since the transistor is switching on and off, would that mean my actual current would be just shy of that? Say 700 milliAmps? If so, is there an equation to predict how much gain a transistor would need to set a true cap of 1 amp.
Thank you!!
