In particular, the notion of the N-step model is introduced to capture the hybrid nature of these systems, and an optimal control problem is formulated, which allows one to easily incorporate in the controller design safety constraints such as current limiting. The optimal control problem is solved offline resulting in the explicit state-feedback controller that can be stored in a look-up table and used for the practical implementation of the control scheme. Simulation results are provided that demonstrate the prospect of this approach.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

When active correction is not used and converter regulation is the main control objective instead, poor power factor results. It is shown that a tradeoff between power factor and filter size can be supported. Through computer analysis, it is found that there is a specific supply current waveform that should be used to achieve a given power factor target with minimum filter size. For reasonable power factors (such as 70% to 100%), the current waveforms meet requirements in IEC 61000-3-2 over a wide range of supply power level. The results point the way to reduced cost power supplies.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

The presented algorithm is capable of not only extracting the fundamental component from the voltage or current signal containing harmonics, but also tracking the fundamental frequency and phase, which can supply the synchronizing reference signal for the system. The theoretical analysis and the practical implementation of this method have been discussed in detail. Its high filtering performance and fast dynamic response have been verified by the simulation and experiment. In this paper, a laboratory prototype of the current-source active filter is built, which employs the proposed technique to generate the current reference signal for harmonic compensation, and the voltage synchronizing reference signal for DC side active power control.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

The bandwidth of the reduced order model can be specified and changed at the users' discretion, even during a simulation run, yielding multiple resolutions and simulation speeds.

The main advantage of the proposed method is that studies can be done for any solar array configuration formed from elementary models of solar cell units. Hierarchical structure of solar cell elements with semiconductor detail allows simulations of electrical properties as well as evaluation of environmental conditions impact. Application examples such as the effect of unequal illumination on various array interconnections and the mismatch of solar cells are presented to demonstrate the usefulness of the tool. The automated process eases investigation of large system and worst-case study for given environmental scenarios.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

Three examples using the same hardware in diverse areas of power electronic control demonstrate that this technique allows the implementation of demanding state-of-the-art power electronics systems, with the important benefit of a much reduced development time and increased reliability.
