A complex vector model for three-phase SVPWM voltage-source converter is presented in this paper. It has been proved more convenient to compare the performance of different current controller topologies in the synchronous rotating frame by means of complex vector root locus and complex vector frequency-response functions. An improved synchronous rotating PI current controller is proposed, whose validity and feasibility is verified by detailed simulation and experimental results.

The switching characteristics (turn-on and turn-off) and forward conduction drop of trench-gate IGBTs are examined over a temperature range of -260 to 25/spl deg/C. A physics-based model previously developed is modified to incorporate appropriate physical behavior at low junction temperatures. Results from the model are compared to experimental waveforms and discrepancies are discussed.

This paper proposed a simple solution to the variable switching frequency and high torque ripple problems encountered in hysteresis-based DTC drives. The method replaces the hysteresis-based controllers with fixed switching controllers, which operate based on the comparison between the error signals and the triangular waveforms. Implementation of these controllers using digital circuits is highly suitable since they only require comparisons of waveforms rather than calculations of duty cycles or voltage vectors. Modeling and simulation of the DTC drives using these simple controllers are presented and the results show that they are capable of reducing the torque ripples significantly.

Power factor correction (PFC) converters for the higher power range are commonly designed for continuous conduction mode (CCM). Nevertheless, operation in the discontinuous conduction mode (DCM) occurs for light load in a zone, close to the crossover of the line voltage. This zone will gradually expand with decreasing load to finally encompass the entire line cycle. Whereas in CCM the parasitic capacitances of the switches only cause switching losses, in DCM they are a source of converter instability, resulting in significant input current distortion. In this paper, this source of input current distortion is analyzed and a solution is proposed. Experimental results are obtained using a digitally controlled boost PFC converter, designed to operate in CCM for 1 kW.

Based on a new definition of nonactive current/power, this paper presents the application of a parallel active filter for the compensation of nonperiodic currents. Analysis of the compensation characteristics required for a variety of nonperiodic currents such as those associated with arc furnaces is presented. In addition, the corresponding current rating and energy storage requirements of the compensator are also presented.

This paper presents a 2 kW three-phase dual active bridge converter (DAB3) which converts power between 42 V and 300 V and is easily scalable up to 20 kW. The DAB3 has been selected for this application based on detailed simulations comparing different suitable topologies. The circuits investigated in this paper can operate in a soft-switching manner enabling a reduction in device switching losses and therewith an increase in switching frequency. Candidate topologies under investigation are the serial resonant converter (SR), the single-phase dual active bridge (DAB1) and the three phase dual active bridge (DAB3). Key-features are the galvanic isolation, reduced cooling costs, and the capability of transferring energy over a wide voltage range.

A fuzzy logic controller for an active power line conditioner (APLC) is described. Frequency-domain analysis is used to determine the desired compensation current, and a rule-based piecewise linear fuzzy proportional-integral controller (FPIC) provides the appropriate switching pattern of the APLC to generate the actual compensation current. Both MATLAB simulations and experimental measurements on a low-power, digital signal processor (DSP) based, hardware prototype are described. The simulations and measurements agree very well and show that the APLC/FPIC system can significantly improve both total harmonic distortion and power factor during both steady-state and transient operating conditions.

Due to the current concern about the environment, there is a growing interest in distributed generation from renewable energy sources. Usually a power electronic converter is required to interface renewable generation units with the utility grid. The power electronic converters can be designed to provide nonactive power in addition to active power supply in order to compensate distorted currents. This paper proposes a distributed control method for converter-interfaced renewable generation units with active filtering capability. Agent-based communication makes coordination between the generation units possible. Experimental results are included to demonstrate the validity of the proposed method.

This paper presents the theoretical analyses and experimental comparisons of different solutions aimed at minimizing and canceling common-mode (CM) currents, shaft voltages and bearing currents. In particular, it discusses the use of CM chokes for minimizing CM currents; illustrates the use of a shaft-grounding method combined with a CM choke; analyzes the effectiveness of the "passive" method of the CM transformer (CMX); and evaluates the "active" method of the CMX that effectively cancels the CM voltages (and thus simultaneously the CM currents, shaft voltages and bearing currents). The latter is the best solution to both CM (EMI) and bearing current problems at the expense of being the most costly. Experimental results are presented to substantiate the theoretical analyses.
