The invention provides a noncontact electric energy and signal synchronous transmission system and a control method thereof, wherein the noncontact electric energy and signal synchronous transmission system and the control method belong to synchronous transmission systems and control methods thereof. The noncontact electric energy and signal synchronous transmission system comprises a DC voltage link, a high-frequency inversion link, a primary side energy conversion link, a secondary side energy conversion link, a primary side signal modulation link, a secondary side signal demodulating link and a load. The high-frequency inversion link is parallelly connected with the primary side energy conversion link and the primary side signal modulation link, thereby respectively forming a fundamental wave extraction channel and a third harmonic extraction channel. Through switching on and off a switching device in the primary side signal modulation link, the signal is loaded in a third harmonic channel circuit. A signal current is coupled with the primary side energy conversion link through a unity-coupled transformer. After an energy current and the signal current are simultaneously transmitted to the secondary side by a same loose coupling magnetic path mechanism, the energy current is separated from the signal current through the secondary side energy conversion link and the secondary side signal demodulating link, thereby realizing simultaneous transmission of the electric energy and the signal. The noncontact electric energy and signal synchronous transmission system and the control method thereof further have advantages of stable output power, high signal transmission rate, small size and high efficiency.

Light flux levels sensed from a color LED array control both current availability to the array and disable/re-enable a current bypass switch to shunt stored-energy current to or away from a selected LED. In continuous mode, a single flux pulse is created for the duration of a pre-established period. Feedback from the flux sensor pulses current to an energy storage device to maintain the light flux at a predetermined set-point. A particular dimming level is achieved by establishing both the pulse period and the flux magnitude. In discontinuous mode, one or more short flux pulses are created. Both the turn-on and the turn-off time of each flux pulse is controlled by alternately removing and then re-establishing a current shunt from the energy storage device to ground. Flux pulse magnitude is controlled by recognizing when the flux pulse has reached a predetermined set-point and re-establishing the current shunt to abruptly turn off current to the selected LED.

An asymmetric alternating voltage (preferably 40 KHz) is provided between a pair of targets having a coaxial (preferably frusto-conical) relationship to (1) deposit the material in a uniform thickness on the substrate surface (2) eliminate dielectric material from the surfaces of the targets and other components (3) provide a single ignition of the targets and eliminate target ignitions thereafter and (4) reduce the substrate temperature by using low energy (“cold”) electrons from a plasma discharge to produce a low energy current. The asymmetry may result from amplitude differences between the voltage in alternate half cycles and the voltage in the other half cycles. A second alternating voltage (preferably radio frequency) modulates the asymmetric alternating voltage to provide the smooth plasma ignition. The different voltage amplitudes applied to each of the targets are also instrumental in providing for a substantially constant deposition thickness at the different positions on the surface of the substrate.
