Abstract: Interleaved Boost converters (IBC) serve a number of applications, which require a boost in the output voltage such as the distributed generators (DG´S), high voltage battery chargers etc. This paper brings out the design and simulation of a high efficiency two-phase interleaved DC-DC converter with an efficient MPPT controller. The configuration of interleaved boost converters comprises parallel combination of a number of boost converters with phase shifted PWM signals. The advantages of interleaved boost converters compared to conventional boost converters are reduction in output ripple voltage, ripple current and high efficiency. The current ratings of switching devices are considerably reduced due to the high frequency operation, which in turn helps in the reduction of overall cost. The performance parameters of the proposed interleaved boost converter are analyzed by MATLAB simulation.
