Abstract
- This paper proposes a new harmonic current-free ac/dc power conversion system characterized by the integration of a small-rated series active filter with a large-rated double-series diode rectifier. The dc terminals of the active filter are directly connected in parallel with those of the diode rectifier, thereby forming a common dc bus. The active filter enables the diode rectifier to draw three-phase sinusoidal currents from the utility. In addition, it can provide the supplementary value-added function of regulating the common de-bus voltage to a limited extent of [+ or -]5%, slightly increasing the rms voltage rating, but not increasing the peak voltage rating. Experimental results obtained from a 5-kW laboratory system verify the practical viability and cost effectiveness of the proposed system. Index Terms - Diode rectifiers, harmonic currents, PWM inverters, series active filters.
