Samlex SDC-5 Switching DC-DC Converter 20-32 VDC- 5 Amps

in this video we're gonna talk about the buck converter circuit so let's draw the schematic of the circuit the first thing we need is a voltage source now we're gonna use a battery for that next we need a switch which we'll call s1 and parallel to the battery we need a diode and then we need an inductor and a capacitor the purpose of the capacitors to maintain a relatively stable output voltage across the load resistor so this is going to be RL C and D 1 let's use a 12 volt battery in this example so this is the buck converter circuit this circuit works by reducing the voltage at the input now there are a lot of other circuits that can reduce the voltage such as a voltage divider circuit using two resistors or even Zener diodes and linear voltage regulators you can use them to not only reduce the voltage but maintain a constant output voltage as well but those types of devices they redu
