Three Phase AC Voltage Cuk Converter with Galvanic Isolation

In this paper, a three-phase Cuk voltage converter with galvanic isolation is investigated. This converter can be referred to a power electronic transformer. The analysis determines the adjusting and external characteristics. And also the dependence of the input power factor on the duty cycle. The process of galvanic isolation and transformation is transmitted to high frequency. As a result, mass and dimensions parameters become better. The spectrum of the converted voltage of the transformer does not contain harmonic frequency of power voltage but only mixed harmonic generated by high frequency commutation.
