ABSTRACT: This paper describes about a design and simulation analysis of Interleaved Buck Converter in network communication for Femto Technology. The evolution of wireless broadband technology improves the data speed and coverage and avoids the web surfing of the network which can be done by using Femtocells without the need of the expensive cell towers. They are low power consumption of 12V for 3G, 6V for 4G ,5V for 5G and low-cost user deployed base station able to provide high service in residential, enterprise and metro cells. In the hardware architecture of the femto cell, the DC-DC converter such as Buck converter plays a important role which converts from the higher voltage to lower voltage towards the supply side of the femto cell. In this converter, the switching losses and inductor AC losses are more, efficiency is less, power density and pf are less. In order to overcome from these limitations, interleaved buck converter has been introduced which has low switching losses & improves step down conversion ratio suitable for high input with the duty ratio less than that of 0.5%. A closed loop control is achieved by designing a digital PID controller to achieve the proper regulator for this converter. For the enhancement in updating the technology, this converter is connected to the GPRS IOT for the improvement in the network strength. The design and analysis of the closed loop control of the Interleaved buck converter with the input voltage of 12V and output voltage of 5V with the power rating of 10W for the Femto technology has been discussed. In this proposed paper the hardware architecture of the femto cells along with the design and analysis of the closed loop Interleaved buck converter with the GPRS module has been validated.
