    An automatic lamp detection technique for electronic ballasts

    , Conference Proceedings - IEEE Applied Power Electronics Conference and Exposition - APEC, Vol: 1, Pages: 575-581

    Based on a comprehensive comparison of fluorescent lamp parameters of major lamp manufacturers, this paper presents an automatic lamp power detection method that can differentiate the lamp power of tubular T8 and T12 fluorescent lamps. This method can be easily incorporated into existing electronic ballast control so that the same electronic ballast design can operate different lamps at their respective rated power levels. With this patented method, a universal electronic ballast can be designed to operate the full range of T8 and T12 fluorescent lamps from 18W to 70W without any power mismatch problem. Design criteria and practical verifications are included to confirm the theory behind this lamp power detection method. © 2005 IEEE.

    Energy efficiency comparison of dimmable electromagnetic and electronic ballast systems

    , Conference Record - IAS Annual Meeting (IEEE Industry Applications Society), Vol: 4, Pages: 2775-2781, ISSN: 0197-2618

    Compared with electromagnetic ballasts, electronic ballasts have much shorter lifetime and are not recyclable. This prompts new concerns about their environmental impacts due to the accumulation of toxic and non-biodegradable waste components and materials. In this paper, the combined use of a central dimming system with low-loss electromagnetic ballasts is compared with electronic ballasts. Experimental results have confirmed that the use of a central dimming system for large electromagnetic ballast driven lighting systems can be as energy efficient as electronic ballasts. Considering the long lifetime of electromagnetic ballasts and recyclability of their magnetic chokes, this project shows that such combined technology can provide an improved environmental-friendly and energy-saving solution for large-scale electric lighting systems. © 2005 IEEE.

    A three-dimensional space vector modulation scheme for three-level three-wired neutral point clamped converters

    , PESC Record - IEEE Annual Power Electronics Specialists Conference, Vol: 2005, Pages: 2307-2314, ISSN: 0275-9306

    Three-level converters have been used for dc-ac conversion when the desired ac voltages are balanced. To deal with the unbalanced situations, three-level four-leg converters have been proposed. The four-leg converters use an extra leg to conduct any neutral current in a three-phase four-wire system. More switching devices in the four-leg converters result in increased cost and possibly increased switching losses compared with the three-leg converter. In this paper, a 3-D space vector modulation scheme for three-level three-leg is proposed to deal with unbalanced situations. This scheme uses existing topology and does not require any hardware modification. It is also suitable in applications where neutral is not required such as STATCOM, UPFC etc. Simulation and practical results have confirmed that the proposed 3-D space-vector scheme has better low-order harmonic performance than traditional 2-D scheme under unbalanced conditions and less switching transients in the voltage balancing capacitors in the 3-level inverters. These potential advantages could enable cost and size reduction in the site implementation of passive filters and prolong the lifetime of the inverter equipment. © 2005 IEEE.

    An analysis of a double-layer electromagnetic shield for a universal contactless battery charging platform

    , PESC Record - IEEE Annual Power Electronics Specialists Conference, Vol: 2005, Pages: 1767-1772, ISSN: 0275-9306

    A patented double-layer planar structure is employed to shield the electromagnetic (EM) field at the bottom of a universal charging platform. The double-layer consists of a layer of soft ferromagnetic material and a layer of conductive material. Thin 4F1 ferrite plate and the copper sheet are used in this example. This shielding technique is analyzed with the extended transmission line theory. With the formulas presented, the shielding effectiveness (SE) of both single-layer shield and double-layer shield could be calculated out directly, without using finite-element software. A classical transmitting-receiving loop measurement has been carried out to evaluate the SE of single ferrite shield, single copper shield and double-layer shield respectively. Calculated and measured results in the working frequency range of the charging platform from 100 kHz to 500 kHz confirm that the double-layer shield has obviously better SE than single-layer shield and can achieve a SE above 40dB, which is commonly accepted by the industry. Finally, the potential of this double-layer shielding technique for a wide range of power electronic applications is discussed. © 2005 IEEE.

    Equivalent circuit modeling of a multilayer planar winding array structure for use in a universal contactless battery charging platform

    , Conference Proceedings - IEEE Applied Power Electronics Conference and Exposition - APEC, Vol: 2, Pages: 1366-1372

    In this paper, an equivalent circuit model of a multilayer planar winding array structure that can be used as a universal contactless battery charging platform is presented. This model includes the mutual-inductive effects of partial overlaps of planar windings in the multi-layer structure. It has been successfully simulated with PSpice and practically verified with measurements obtained from three prototypes. This circuit model forms the basis of an overall system model of the planar charging platform. It is demonstrated that model parameters can be derived from the geometry of the winding structure. Errors between the calculated and the measured results are found to be within a tolerance of 5%. © 2005 IEEE.

    Finite element simulation of a universal contactless battery charging platform

    , Conference Proceedings - IEEE Applied Power Electronics Conference and Exposition - APEC, Vol: 3, Pages: 1927-1932

    This paper presents a finite-element (FE) simulation study of a planar contactless battery charging platform for portable consumer electronic equipment. Magnetic field plots of the charging platform are generated under no-load and loaded conditions so that the field distribution of the planar charging platform can be visualized. With new results arising from this FE simulation study, the theory of the mmf generation of the multilayer planar printed-circuit-board (PCB) winding array structure can be further understood. Experiments have been carried out to identify the loading effects and central field sag phenomenon. Magnetic field variation at the edges of the platform can now be explained. It is found that a patented shielding structure is effective in suppressing the EM field at the bottom of the charging platform. Most importantly, the FE simulation confirms the 'pancake' shape of the field distribution in the planar charging platform. Such prediction is verified with practical measurements. © 2005 IEEE.
