The series-resonant energy-tank is used as the starting-aid circuit to eliminate the glow current in the lamp during the preheating interval. By adjusting the operating frequency, the electronic ballast is able to provide an adequate filament current for preheating with nearly zero lamp voltage, a lamp voltage high enough for ignition, and then the required lamp power and filament current at steady-state. A prototype of the electronic ballast with the proposed control scheme is built for a T8-36 W fluorescent lamp. Experimental tests exhibit satisfied results.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

As a possible way to overcome these problems, this paper provides an overview of an integrated approach to design and realize power electronics systems, aiming at improved performance, reliability, manufacturability and cost effectiveness. A brief discussion is presented on the technology barriers that limit the rapid growth of power electronics, such as passive components and packaging techniques. It is also discussed the technology advancements needed to improve the characteristics of power electronics systems, such as increased levels of integration, standardization of parts and improved packaging techniques for enhanced thermal management and electrical performance. The technologies being developed for the realization of integrated systems include planar metalization to allow three-dimensional structural integration of power devices and control functions, integration of power passives, and integration of electrical/thermal design tools.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

The suitable converter output voltage can be obtained by compensating the unbalanced condition and the harmonics with using the phasor representation expression.

Motor features prove to depend mostly on the elimination or keeping the running capacitor in series with the auxiliary winding, as well on the chosen voltage-frequency profile (in open-loop control). The market requirement for low-cost topologies affects the drive performance, since a capacitor-less motor appears to be the best solution, but it requires a higher voltage for the auxiliary winding. The permanent split-capacitor motor offers a good compromise if the V/Hz dependency is in accordance with the maximum efficiency or the minimum pulsating torque optimisation criteria. Finally, inverter topologies suitable for low-cost, single-phase induction motor drive systems are analysed and tested, both in simulations and experiments. It is concluded that the elimination of the running capacitor provides an advantage only if the stator asymmetry is smaller or inexistent, as is the case of the symmetrical motor. Therefore, by keeping the running capacitor in series with auxiliary winding and compensating for the increasing of its reactance at low speeds, may lead to a competitive solution in application areas with no tough demands for high performance, such as pumps and fans.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

The authors proposed the low frequency AC (LFAC) cable transmission to meet with that requirement. A cycloconverter can be applied to convert from utility AC frequency to low frequency for LFAC system. However, the output of the cycloconverter presents discontinuous current conduction because of the capacitive characteristics of the cable transmission line. This paper proposes the novel cycloconverter control system, which enables stable operation of the noncirculating current control to the capacitive output circuit, and proposes the three-phase output balancing control. The power flow control of the LFAC system by the cycloconverter is also confirmed through computer simulations.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

By the proposed modulation scheme the DC-link voltage can be actively controlled to maintain a stable neutral point even if unbalanced loading of the DC-link capacitors occur due to e.g. nonlinear loads containing even harmonics. The maximum unbalance for which the modulation scheme are able to compensate is theoretically investigated and found to be a function of both load angle, modulation index and output power level. The proposed modulation method is compared to conventional modulation schemes with regard to both switching losses and wave form quality. For the same number of switchings, the proposed modulation scheme offers up to 25% lower switching losses than conventional modulation schemes while maintaining the same output wave form quality. The functionality of the modulation scheme is validated by simulation results.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

In the simulation environment of SABER, the circuit statistical analysis at randomly selected device parameters under certain tolerance bounds is illustrated in detail with a flyback convertor and an active band pass filter as examples. Moreover, the simulation wave and statistical summary are presented. Based on the statistical analysis results, the robustness of the circuit is appraised and the proportion of finished product in the batch production is forecasted.
