    摘要： A driving device for a LED module is provided. The driving device for the LED module includes a voltage converting unit, a LED module voltage detecting unit, and a switching signal generation unit. The voltage converting unit produces a driving voltage to drive the LED module according to a switching signal. The LED module voltage detecting unit divides the driving voltage to produce a comparison voltage. The switching signal generation unit receives the comparison voltage by a fault detection pin and compares a reference voltage and the comparison voltage to enable or disable the switching signal. After the switching signal is disabled, the switching signal generation unit further pulls up a voltage level of the fault detection pin to a logic high level voltage, so as to produce a fault notification signal to let the fault detection pin also have a function for fault notification.

    摘要： An islanding detection and protection method of a parallel-type power converter is proposed, which performs perturbation to a power system to detect the frequency of the system voltage and the variation of the magnitude of the negative-sequence voltage as the basis for deciding the occurrence of an islanding operation. When the system operates normally, the frequency or phase and magnitude of the system voltage and the magnitude of the negative-sequence voltage won't be affected by the perturbation. On the other hand, if an islanding operation occurs, this perturbation will cause an apparent drift of the frequency or phase and magnitude of the system voltage and the magnitude of the negative-sequence voltage. Through detection of this apparent drift, the perturbation can be amplified by means of positive feedback to quickly detect the islanding operation phenomenon and trigger the protection mechanism.

    摘要： A battery energy balance circuit and a battery charging bypass circuit is disclosed for batteries being charged at the same time to be charged equally. When the terminal voltages of the batteries are different, a controllable power device switch in the circuit switches on and off at a high frequency in order to reduce the input current to the batteries with higher terminal voltages and to increase the input current to the batteries with lower terminal voltages, achieving the goal of equal charging. The disclosed energy balance circuit can avoid damages to the batteries as a result of overcharging. When the number of batteries increases, one can expand the system in a modularized way to prevent inconvenience of circuit designs.

    摘要： A fabrication method and a structure of a flash memory. Several first shallow trench isolations and second shallow trench isolations are formed in a memory circuit region and a peripheral circuit region of a substrate, respectively. The first shallow trench isolations are shallower than the second shallow trench isolations. Several gates are formed along a direction perpendicular to the substrate in the memory circuit region. A self-aligned source region process is performed to remove the isolation layer within every other first shallow trench isolations between the gates. A common source region and a column of separate drain regions are thus alternatively formed between the gates. The drain regions in the same column are isolated by the first shallow trench isolations.
