, the reliable and stable new power supply should be replaced.2, optical drive reading disc performance is not good. This situation generally occurs in the newly purchased computer or the newly bought CD-ROM, the reading of the disc with a huge hum, troubleshooting the optical drive, it is likely that the power

shock, which brings great inconvenience to the users in the process of use. In order to protect the switching power supply itself and the load, according to the principle and characteristics of DC switching power supply, the design of overheat protection, overcurrent protection, over-voltage protection and soft start

incidents, cause immeasurable losses. Advantages and disadvantages of regulated power supplyAdvantages:[1]. low power consumption and high efficiency. In the switching regulated power supply circuit, the transistor v works alternately in the switching state of conduction-cutoff and cutoff-conduction under the excitati

filtering, you can obtain a relatively smooth and stable voltage, so that the output voltage reached the CPU supply voltage requirements. The physical figure of the CPU power supply is shown in Figure 2. The 12V Electric Music of the host power

is generally. Therefore, when designing a power supply cabling system, a dedicated power supply line must be provided for the air conditioner. 2. COMPUTER: Generally, in the design of the Internet cafe Power System Wiring, it is

first and second coils of the switch transformer. If you reverse the end of the initial or secondary coil of the switch transformer, Figure 1-17 will no longer be the active transformer switching power supply.We can see from (1-76) and (1-77) that changing the duty cycle D of the control switch K can only change the average UA of the output voltage (1-16-B, the amplitude of the output voltage remains unchanged. Therefore, the switch

, and the thermal stress and thermal shock are small. However, the main disadvantage of this method is that the size and weight of the heat sink are large. The transformer's bypass mechanism is to minimize the temperature rise and prevent the temperature rise from affecting its performance. Therefore, the material selection margin is large, and the transformer's volume and weight are also large. The material cost of the rectifier is high, which makes maintenance and replacement inconvenient. Due

point of the switch to burn out, the rectifier bridge over-current damage, the light will also make the air switch can not close the brake. All of these phenomena will cause switching power supply does not work properly, for this reason almost all switching power supplies are set to prevent inrush current soft start circuit to ensure that the second-hand robot

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

Are you going to have a power supply to get him powered on without a motherboard? The ATX 20pin has a non-stop bayonet on it, and it's facing itself, and then it's down to the left of the line. 4th and right, 4th, get these 2 connected. Green and any one black, black is ground! Special attention: 1, the PC 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 tech

The power distribution system should meet the requirements of the Information Equipment Room, ensure the reliability and flexibility of power supply, ensure personal safety, facilitate construction, maintenance and management, and achieve advanced technology, economic and reasonable. The lighting system complies with relevant national regulations. More integrated

The standard power-saving Master also features a patented technology that adds an energy-saving power

Design of power supply in high-speed circuitThe design of power supply in high-speed circuit is probably divided into two kinds, one is lumped architecture and one is distributed architecture. A lumped architecture is a power input that generates a variety of required voltag
