A New Line Harmonic Reduction Technique for Single-Phase Single-Stage Converter Using Parallel Power Processing

Abstract A new line harmonic reduction technique for single-phase single-stage converter is proposed. Using parallei power processing. this converier showsiow link voltage stress under wide line and load changes while providing a good power factor and efficiency. The experimental results show that the maximum link voltage stress and efficiency are about 447 V and 81%. respectively. Experimental results show that the power factor is above 0.96 under the universal line condition at full load and the maximum link voltage stress is 385 V. The proposed converter is suitable for low cost and compact power supplies below several hundreds watts and universal line applications.
