This work proposes a new interleaved buck converter (IBC) which maintains a constant output voltage to a specified value with a PID controller. The PID controller varies the duty cycle of the switches to regulate the output voltage. The proposed converter has low switching losses, reduced voltage stress and high step-down conversion ratio which is suitable for the applications where the input voltage is high. Here, two active switches are connected in series with a coupling capacitor in the power path which operates below 50% of duty ratio to reduce the voltage stress of the active switch to half the input value before turn on and after turn off. As a result of this the switching losses and capacitive discharge losses are reduced. Hence the efficiency of the converter is increased.
