Fuel cells needs high step up ratio dc-dc converter. This is because, such energy resources generates low dc voltage which needs to be converted into high dc, before converting to ac voltage. Two modified SEPIC converters for low input voltage and high output voltage application topologies are studied and they results in reduced switching voltage and increases the static gain. The configurations with and without magnetic coupling are analysed. The magnetic coupling allows the increase in static gain than the circuit without the magnetic coupling and maintains the reduced switch voltage. Simulation is done using MatlabR2014a. experimental prototypes of modified SEPIC converter with magnetic coupling were developed with input voltage equal to 8V. The circuit with magnetic coupling gives an output voltage of 160V. The configuration with magnetic coupling is modified for obtaining dual output.
