Latest Patents

One of Yu-Pei Huang's latest patents is a control system for multiple fluorescent lamps. This invention is directed to an apparatus that drives a lighting system with multiple lamps. A phase shift mechanism is produced either by a digital method, an analog method, or a mixture of the two methods. In the digital method, phase shifts are generated by digital circuits comprising counters, a divider, an adder, and a comparator. The digital circuits analyze the signal and use the necessary information to form a series of phased driving signals. In the analog method, phase shifts are generated by analog circuits comprising ramp waveform generators, comparators, and at least one shot generator. Additionally, an apparatus for driving a lighting system with multiple lamps can be realized by mixing the two methods mentioned above.

Another significant invention is a high-efficiency and low-cost cold cathode fluorescent lamp driving apparatus for LCD backlight. This invention is a driving apparatus and circuit for efficiently converting a direct current (DC) signal into an alternating current (AC) signal to drive a fluorescent lamp. A semi class E configuration, which utilizes only one transistor, is employed in the invention. The invention comprises a power transistor, a transformer wherein a primary winding is used as a load for the power transistor and a secondary winding is used to transfer energy to the load for the driving apparatus, i.e., the CCFL tube, and control means which extracts the frequency and current of the power transistor and corrects the deviation between the frequency of the power transistor and that of the control means.
