摘要： A multiplier multiplies a current signal of an Iy generator and a voltage signal from a Vx generator corresponding to a divided voltage value of an output voltage of a full-wave rectifier. The result of the multiplication is output as a current reference signal to the non-inversion input terminal of a current error amplifier. A current peak waveform generator circuit generates an envelope waveform of peak values of an inductor current. An Iz generator, when the envelope waveform exceeds a first threshold value smaller than a third threshold value set in an overcurrent protection circuit, curbs the inductor current by adjusting the size of a current signal output to the multiplier, and reducing the current reference signal.

摘要： A power factor correction type switching power supply unit can change reference values of an overcurrent limit at an optimum timing at a time of an overcurrent protection of a step-up type converter, so that no sudden change occurs in an inductor current. A detection level selection circuit selects one of first and second threshold values with a selection signal, and outputs it as an overcurrent detection level to an overcurrent detection circuit. An input voltage monitoring circuit determines the selection signal in such a way that the larger of two threshold values is selected when an alternating current input voltage exceeds a first reference voltage, and the smaller threshold value is selected when the alternating current input voltage does not exceed a second reference voltage, and outputs the selection signal to the detection level selection circuit at a timing at which the alternating current input voltage approaches a zero.

摘要： The embodiment of the present invention provides a method for establishing a route, which includes searching a target node by a node from a first level node group according to first level route information, returning to query a result or data saved by the target node if the target node is found, otherwise executing the following step; searching a target node by the node from a higher level node group according to higher level route information, returning to query a result or the data saved by the target node if the target node is found, otherwise repeating the step. Through the hierarchical communication system, most of the flows of daily service operations in the communication network are limited within a small region, thereby preventing from excessively occupying the band width of a backbone network being originally not wide enough.

摘要： The invention provides a switching power supply device which can detect a light load state on a pulse-by-pulse basis without worsening power efficiency. In a synchronous control circuit, for each timing of the turning-on of main switching elements, the delay time Tdif of the conduction timing of internal diodes Ds determined according to the magnitude of the load LD is detected by a comparator, a reference time pulse Tsrs having a prescribed time width is generated by a load judgment circuit, and the logical product of the two is generated by an AND circuit. By this means, the load is regarded as being a light load when the delay time Tdif is longer than the reference time pulse Tsrs, and the synchronous rectification MOSFETs Qs are not turned on.

摘要： In order to overcome the defects of the centralized subscriber data management in the telecommunication network, a highly effective distributed data management system for the communication network is achieved in the present invention through improving and applying the distributed Hash table (DHT) technology to subscriber data management in the communication network, which overcomes the deficiencies of the conventional centralized data management. A method for processing subscriber data in a communication network based on a DHT is provided, which includes the following steps. A first node in a DHT overlay network receives subscriber data to be stored. The subscriber data to be stored is regarded as backup data divided into L/K portions. L is greater than or equal to a ratio of a node working bandwidth of a second node to a node recovering bandwidth for data recovery of the second node in the DHT overlay network. K is a total number of backup data and is an integer greater than zero. The subscriber data to be stored is regarded as master data, and the master data and K×L/K divided backup data are, respectively, stored in 1+K×L/K DHT nodes.
