Abstract

In this paper, two kinds of the protection circuits are proposed and simulated to verify their performances. One is an over current protection circuit, and the other is a no load protection circuit which reduces power consumption. These protection circuits of an LED drive circuit can reduce power consumption and prevent to damage the elements.
