This study presents a non-inverting buck-boost converter with an interleaved technique for fuel-cell systems. The converter transforms the fuel-cell energy into an electric current for efficiently running electric mobility systems. Two non-inverting buck-boost converters are integrated with an interleaved operation. Thus, a switch and a diode can be omitted, reducing cost. The interleaved operation reduces both the current ripple at the output and the current stress of the diodes. The operating principles and steady-state analysis are discussed in detail. An 800 W prototype circuit of the proposed converter that converts an input source (fuel-cell battery 24-45 V) into an output voltage (28 V) is built to verify performance. The synchronous rectifier technique is adopted to increase efficiency. Power loss and efficiency are also discussed.
