Some electrical appliances contain coil components, which may lead to Eddy Current blocking during the initial power-on period. The generation of eddy current will weaken the transient voltage at the startup of the electrical appliance, resulting in slow start, the transient voltage generated after circuit breaking is enhanced, and the circuit may be damaged by sparks.In this case, add the Link Description for the Single-Phase Frequency Conversion

Notebook its own biggest bright spot is convenient to carry, generally speaking when we use the laptop in the external power supply, the battery suggests the best to put inside, because the general battery is full of electricity, basically in a dormant state, the overall impact on the notebook life is quite small, generally we can ignore, In addition laptop and notebook battery life is basically equal, that

Have you ever designed a power supply that has a good load transient response in a light load state? If so, and you also allow the power to be discontinuous, you may find that the gain of the control loop drops sharply under light load. This results in poor transient response and requires a large number of output filter capacitors. Have you ever designed a

As117 provides 1A Linear Power Supply: 144 pin, less than 50 thousand doors As2839 and lt1085/6 provide 3A Linear Power Supply: 240 pin, 0.3 million logic gate or lower Tps54350 provides 3A Current Switching Power Supply: Suitab

are used to filter out low-frequency signals in the current. However, even low-frequency signals have frequencies of several orders of magnitude. Therefore, in order to be suitable for use at different frequencies, electrolytic capacitors are also divided into high-frequency capacitors and low-frequency capacitors (the High Frequency here is relative). The low-frequency filter capacitor is mainly used for filtering mains filtering or transformer rectification. Its working frequency is the same

The company's computer is idle with two hard disks. I want to put these two hard disks on a celon D machine. This machine has a power supply of 250 W, it is estimated that the actual output power may be less than 200 W. A hard disk and an optical drive were previously attached. After the hard disk is loaded, the machine starts and can identify three hard disks a

size of the gate drive voltage, the driving voltage increases, the resistance becomes smaller. Detailed relationship curves can be obtained from the manufacturer's manual. This working condition, known as the synchronous rectification of the MOSFET, is a very important working condition in the low voltage high current output switching power supply. Forward cutoff equivalent circuit of

To ensure the long-term normal operation of the Frequency Conversion Power Supply, necessary inspection and maintenance should be timely, and the inspection and maintenance methods should be appropriate. Inspection and maintenance are divided into two aspects: Routine inspection and maintenance and regular inspection and maintenance. There are both differences and internal links between routine and regular

Enterprise Data Center is now more and more important, how to ensure the stable operation of enterprise data Center has become a key factor, UPS is currently a lot of enterprises in the data Center standard accessories, then how to choose a suitable enterprise application of UPS power. categories of UPS In general, the UPS system is divided into three categories, for back-up, on-line interactive and online. Different vendors will provide different co
