Self-oscillating interleaved boost regulator with loss free resistor characteristic

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.
