This paper proposes the design and implementation of a 10 kW hard-switching dc/dc booster converter. The maximum operating efficiency and power losses allocation of circuit elements used in the converter are also explored. Switching transients in the boost converter are also considered and reduced by using a snubber circuit. An L-C filter is used at the output terminal of the converter to achieve stable dc output voltage. In order to obtain high conversion efficiency in a high power operating situation, this paper discuses the specifications selection of circuit elements used in the converter. Finally, a 10 kW hardware prototype is implemented. Use of an infrared thermal imagine analyzer identifies energy losses of circuit elements in the converter. Experimental results show that the conversion efficiency can reach above 95% at full power output.
