In recent year Multiphase converter topologies are getting more interest for use in high performance and low voltage applications. In This paperthe two-phase interleaved buck DC-DC converter (IBC) is designed for desired parameters and further by using state space averaging technique small signals models are derived, steady state performance is investigated in MATLAB- Simulink , closed loop control is achieved by designing PID controller to achieve the proper regulator for the converters.. The hardware implementation of two-phase IBC is performed using ARDUINO UNO as micro controller.
