Abstract :
This paper presents an interleaved boost converter which reduces the pulsating nature of the output current and causes the switching ripple in the output voltage to decrease drastically. For a duty ratio of 50%, the circuit acts as a voltage doubler and its dc input impedance has a resistive characteristic. A sliding-mode controller without external reference guarantees stable and robust behavior for the switching regulator
