zboost power supply

source is compared with the ideal excitation source:Increasing the equivalent resistance of the series resonant circuit and reducing the parallel equivalent resistance in the parallel resonant circuit. The consequence is to reduce the quality factor of the resonant circuit. In order to make the Q value of the resonant circuit not affected by the signal source resistance excessively, the resonant impedance of the series resonant circuit is only suitable to work with the low internal resistance s

note Aspects 1. Regularly dust the Power box. The Power box is the most dusty parts, but also regularly add lubricating oil to the computer fan to avoid the fan to produce a lot of noise, the health of people is not good. 　　Note Aspects 2. Recommended to buy a computer when choosing a good quality power supply, such a

The current production of computer motherboards are using switching power supply mode. Switching power supply mode can be divided into: single-phase power supply, two-phase power

The services currently provided by Internet cafes, such as web browsing, online games, online movies, distance education, and other basic services, are all related to the Internet, the quality of the network directly determines the viability of Internet cafes. Therefore, how to plan a high-quality network environment is a key point that Internet cafe operators must consider. Internet cafe Integrated Wiring accounts for a large proportion of the factors, mainly including:

1-6. Switch Power Supply of excited TransformerThe transient control characteristics of the output voltage of the switch power supply and the load characteristics of the output voltage are relatively good. Therefore, the operation is relatively stable, and the output voltage is not prone to jitter, it is often used in

Power supply is a computer's "power Core", is also prone to failure of one of the components, the failure of the manifestation of a variety of forms. For example, after power-on memory parity error is often related to power, but users are generally easily mistaken for comput

Figure 1-7 is another type of tandem switch power supply, which is generally called a reverse series switch power supply. The difference between this type of reverse series Switching Power Supply and general series-connected switc

This article has three parts: CPU Main power supply circuit composition, CPU single-phase power supply circuit Working principle (take HIP6021 power IC as an example), the CPU single-phase power

In the last few installments, we have installed the main parts of the chassis, which will teach you the power source for installing your computer. One, from the appearance of recognition power supply Probably a lot of people know that the main power supplies are: at power

Study on the application of Poe power supply (I.) Introduction to Guan Jinssong PMP 2010-4-2 Poe POE refers to the transmission of data signals to some ip-based terminals (such as IP telephones, wireless LAN access point APS, network cameras, etc.) while the existing Ethernet CAT.5 cabling infrastructure is not changed Ethernet It can also provide DC-powered technology for such equipment. Poe technology can
