Abstract

Four types of boost converters are designed and fabricated and their operational characteristics are analyzed using experimental results. Soft-switching boost converters are designed to satisfy the condition of input voltage 170-265 Vac, output voltage 400 Vdc, output current 5 A, output power 20 W-2000 W, and unit power factor. In addition, parameter values are designed so that system operation can be compared under the similar conditions. The efficiency of the combined inductor soft-switching boost converter was 97.63 % at full load and it was better than that of the other boost converter types. The combined inductor soft-switching converter has simple circuit construction, low switching loss and low EMI resulting from the switching noise, and harmonic distortion.
