Intelligent method for DC bus voltage ripple compensation for power conversion units

A power conversion system having a DC power distribution bus includes multiple power converters connected to the DC power distribution bus with modulation frequencies synchronized so that providing phase shifts between the different modulations has the effect of compensating voltage and current ripples, e.g., reducing voltage fluctuations, across the DC bus.

Phase shifts in which nulls of the modulation cycles of different converters do not overlap (in the time domain) may be particularly effective for DC bus voltage ripple compensation. The novel method for DC bus voltage ripple compensation may be implemented by programming a digital signal processor to control the power converters.

A composite-like AC-to-DC converter has boosting capabilities. The term "composite AC-to-DC converter" has been coined to distinguish a converter using two or more conversion methods in parallel. All the autotransformer designs for the boost topology composite-like system begin with vector diagrams constructed using the tips of the line-to-line voltage vectors. A constructor arc is swung between these tips equal to the length of the line-to-line voltage vector span. The number of autotransformer three-phase outputs is then determined by the number of equally spaced rays drawn from the opposite vector tip to the arc. The intersection of points of these rays with the arc are used to design the composite-like autotransformer's winding's voltage ratios and interconnections.
