I am HongKonger and here sorry for my poor English.
I am doing the school project which is basic voltage-mode boost converter for 5VDC input transformed to 20V at ~25mA for a series of LEDs.
Honestly, I am newbie to Power Electronics. Although i know the basic operation of Boost Converter; when the transistor switch is turned on , the power source cha capacitor is charged by corge up the inductor through the switch, whilist the capacitor discharges to load. hen transistor is turned off, thembined voltage which include power source and inductor, also the load. But i don't know how to build up the discrete circuit with exact components.
I have done some research and found calculator for evaluating the value of components.
Thanks!.
