The efficiency of the DC-DC converters is an important issue which has received great attention in literature works. Nowadays, step up conversion is widely used in many applications like Electric vehicles, Photovoltaic (PV) system, Uninterruptable power supplies (UPS) and fuel cell system. Frequency dependent boost converter and interleaved boost DC-DC converters presents a novel two-stage boost converter with a soft switching operation. The converter units are connected to each other by an inductor known as interleaved inductor as a bridge. This inductor plays an important role in the soft switching operation of the converter by zero-voltage switching. By paralleling the converters, high reliability and efficiency in power electronic systems can be obtained. . Using high frequency converters we can get improved efficiency, reduced ripple voltage, reduced inductor current ripple. Both the converters are simulated using MATLAB/SIMULINK. The converters are tested by varying the frequency with constant duty cycle and varying the duty ratio with constant frequency in Continuous Conduction Mode(CCM). The performance parameters of the converters are compared. A circuit prototype of frequency dependent boost converter is designed and tested to verify the proof of concept. The hardware realization is done using PIC16F877A controller.
