DC-DC converters has wide range of applications in renewable energy systems, hybrid systems, electric vehicles, fuel cells, and industries. Interleaved topology of dc-dc converter has capabilities of correcting power factor, decreasing input/output ripples, and increasing efficiency, and its specifications of capacitors and inductors are reasonable with low voltage and current stress on switches and diodes. This paper presents MATLAB simulation and hardware model of dc- dc buck-boost converter based on interleaved technique. With a desired output prototype of 36V,4.16A and 150W from a fluctuating input supply of 26 to 43V, two interleaved buck and two interleaved boost converter are arranged in cascade connection with a damping circuit. Various specifications of components are derive dusing steady-state analysis and triggering pulses for MOSFETs are generate dusing PIC micro controller. |
