Abstract :
This paper deals with a boost converter for low input voltages in battery or photovoltaic applications. The performance of a dual interleaved boost converter is investigated theoretically and experimentally. In order to increase the power density and to avoid EMI problems caused by the reverse recovery current of the diode, the discontinuous mode is considered only. At first, the steady state performance of the boost converter is investigation by a MathCAD simulation. It is shown that the input current ripple of a boost converter can substantially be reduced in the interleaved mode. A 1KW dual boost converter has been designed, realized and successfully tested in the laboratory. The integrated circuit UCC28220 from Texas Instruments has been used to control the converter. It employs fast current mode controllers and gate drivers for both sub converters. An error amplifier is inserted to stabilize and to limit the output voltage. The measured input current wave of the dual boost, converter is in good agreement to the result of the simulation. The converter shows a high efficiency throughout the whole operation range
