Abstract :
A new low-power single-stage ac-dc converter is proposed in the paper. The outstanding feature of the converter is that it can operate with a sinusoidal input current and a low primary-side dc bus voltage that is much less variable than that found in other single-stage converters. The operation of the converter is discussed in the paper and its various modes of operation are explained in detail. An analysis of the converter´s steady-state characteristics is performed and the results are used in the design of the converter. Experimental results obtained from a prototype converter are also presented.
