In this paper, a competitive three-phase buck-type PFC converter named SWISS Rectifier is comprehensively researched to inhibit mains current distortion. The control structure which would realize PFC function but also introduce harmonic components to mains current is illustrated and improved to achieve better performance. The origin of the mains current distortion occurred at the sector boundaries is analyzed. Advance modulation scheme and damping strategy are proposed to improve mains current quality. A 10kW-100KHz hardware prototype is designed and experiments results are presented to verify theoretical analysis.

“…Predictive controllers with a current sensor, showing immunity to input voltage distortion are utilized in [27]. These approaches are also employed in three-phase PFC in [28] and [29], respectively. The accurate synchronization of the modulation signals with the grid, the harmonics injected to compensate the distortion effect and the implementation of adaptive controllers to find the best response under distorted or non-distorted grid voltage motivate the utilization of digital controllers.…”

The proliferation of non-linear loads and the increasing penetration of Distributed Energy Resources (DER) in Medium-Voltage (MV) and Low-Voltage (LV) distribution grids, make it more difficult to maintain the power quality levels in residential electrical grids, especially in the case of weak grids. Most household appliances contain a conventional Power Factor Corrector (PFC) rectifier, which maximizes the load Power Factor (PF) but does not contribute to the regulation of the voltage Total Harmonic Distortion (T HDV) in residential electrical grids. This manuscript proposes a modification for PFC controllers by adapting the operation mode depending on the measured T HDV. As a result, the PFCs operate either in a low current Total Harmonic Distortion (T HDI) mode or in the conventional resistor emulator mode and contribute to the regulation of the T HDV and the P F at the distribution feeders. To prove the concept, the modification is applied to a current sensorless Non-Linear Controller (NLC) applied to a single-phase Boost rectifier. Experimental results show its performance in a PFC front-end stage operating in Continuous Conduction Mode (CCM) connected to the grid with different T HDV .

“…The advantage of easy implementation and the effectiveness of the average current mode controller for medium power converters in forcing the input current to be near sinusoidal for power factor improvement have been discussed in the literature [13]. A substantial amount of work has been reported pertaining to the three-phase boost converter [14] and push-pull rectifiers [15].…”

In this paper a high performance improved threephase power converter in modular approach for telecom power systems is proposed. The proposed system is formed by three single-phase modules with series connected dc outputs. The series connection of converter yields balanced dc link currents and galvanic isolation with the use of a high frequency transformer. Further it also and provides 6-pulse rectification, both together resulting in a small output filter components. The design methodology of the proposed converter is illustrated with an example. The design concepts are verified by the digital simulation of the proposed converter.
