    摘要： An EMI filter for use between a power source and an electronic product is formed of at least one planar element including a pair of opposed coreless spiral planar windings, and a planar capacitor. This enables the integration of common mode and differential mode filters into integrated planar structures.

    摘要： An EMI filter for use between a power source and an electronic product is formed of at least one planar element including a pair of opposed coreless spiral planar windings, and a planar capacitor. This enables the integration of common mode and differential mode filters into integrated planar structures. Furthermore the planar EMI filter may be combined with an active filter element to provide a hybrid EMI filter comprising both passive and active elements with superior performance.

    摘要： This invention provides an electronic control method for a planar inductive battery charging apparatus on which one or more electronic loads such as mobile phones, MP3 players etc can be placed and charged simultaneously. The power control circuit of the charging pad consists of two power conversion stages. Depending on the nature of the input power supply, the first power stage is an AC-DC power converter with variable output voltage control and a second stage is a DC-AC power inverter with constant current control. The combination of the two stages provides power control of the charging pad and generates AC magnetic flux of ideally constant magnitude over the charging areas within a group of primary windings that are excited.

    摘要： This invention is concerned with the control and design of a LED lighting system that does not need electrolytic capacitors in the entire system and can generate light output with reduced luminous flux fluctuation. The proposal is particularly suitable, but not restricted to, off-line applications in which the lighting system is powered by the ac mains. By eliminating electrolytic capacitors which have a limited lifetime of typically 15000 hours, the proposed system can be developed with passive and robust electrical components such as inductor and diode circuits, and it features long lifetime, low maintenance cost, robustness against extreme temperature variations and good power factor. No extra electronic control board is needed for the proposed passive circuits, which can become dimmable systems if the ac input voltage can be adjusted by external means.
