power of the Reverse type transformer is output and the current flowing through the secondary coil circuit. Figure 1-20 is the switching power supply of the anti-Exciting Transformer. When operating in the critical continuous current state, the input voltage of the rectification is UO, the load current IO, and the magnetic flux of the transformer core, and t
Switching power supply Control mode Switching power supply in normal operation, the load in the external interference will produce fluctuations, how to ensure that the load fluctuations in the condition of the output stability needs to control the knowledge of the theory to solve. In the design of switching
Overview: The entire structure of an automobile is complex, with tens of thousands of parts. However, the basic structure of an automobile can be divided into four parts: Engine, chassis, body, and automotive electronics. The proportion of automotive electronics to total vehicle costs has been rising. Currently, automotive electronics accounts for 15%-30% of total vehicle costs. For some high-end vehicles, automotive electronics accounts for nearly 40%-50% of total costs. With the continuous dev
Power Supply Design of Radar Video Signal Simulator Based on TPS54310 [Date: 2008-10-13] Source: foreign electronic components by Liu Donghai, Ren Yongfeng, Li shengkun [Font:Large Medium Small] 1 IntroductionThe radar video signal simulator is an important device for debugging the radar signal processor. It has the analog environment and target video echo signal functions and is used
A search on Google found an ATX switching power supply consisting of TL494 and LM339 At first glance, more than 3842 of the switching power supply to be more complex in fact, as long as the basic circuit has a certain understanding and a certain imagination to understand this circuit is still very easy First introd
form of heat,In this way, engineers will have a great challenge in design, for example, if the loss is eventually transmitted in the form of heat, thenThe circuit needs to add a larger heat sink, the result is the volume of the power supply becomes larger, and the efficiency of the machine is very low.If switching power supp
The main working process of UPS power supply is filtering and rectifying inverter. In addition, it also includes many auxiliary units, such as charger and battery, microprocessor, and communication interface. Because the UPS power supply is installed between the device and the mains
installed by default, you may not find the sleep or Hibernate options on the computer's shutdown menu. If you are using a power supply that supports both features, right-click the Start menu and choose Power Options. Go to the Select Power Button Feature tab, and then click Change settings that are not currently avail
Internet cafes currently provide services, such as Web browsing, network games, online movies, distance education and other basic services are related to the network, the quality of the network directly determines the viability of Internet cafes. Therefore, how to plan a high-quality network environment, is an Internet café operators must consider a key point, the integrated wiring of Internet cafes accounted for a large number of factors, mainly two major parts:
less than 36 V, and the Safe Current is less than 10mA. 2. The staff on duty need to remove the barrier for work. The required security distance is 0.7 m for 10 k V, 1.0 m for 35 k V, and 110 m for 1.5 k V, 220 k V at 3.0 m. 3. When thunderstorms require inspection of outdoor high-voltage equipment, insulation boots should be worn, not close to lightning arresters, lightning rods and Grounding Devices. 4. When an electrical device is on fire, the power
Nowadays, switching power supply has replaced linear regulated power supply and is active in the electronic power design field. People gradually realized that the switch power supply ha
Summary, in fact, many of the functions are in the System control Panel can be set up, the previous introduction and now introduced from the Start menu into the panel, specifically as follows. 1. Right-click the "Start" icon in the lower-left corner of the desktop mode.2. Select "Control Panel".3. Select "System and Security" in the Control Panel.4. Select "Power Options".5. Select Change Schedule settings on the right side of the
In the past, on-site cabling was very simple. The sensor can be either power-supply or passive. The power supply type requires 2, 3, or 4 cables, and the passive type requires only 2 cables. At the same time, the sensors are both analog-type and support 12, 24, 36, 48VDC, or 110, 220VAC voltages. The field controller p
When buying a computer, you are too concerned about the speed of the CPU, the memory capacity, the speed, and the hard disk capacity and speed, this is also the most transparent, and the majority of businesses are most willing to publicize and boast to use. However, we all ignore a very important issue. The power supply of the PC is the foundation for other components to work normally and stably for a long
One day, I repeatedly started the machine several times, and then pressed the power key, but it didn't respond. After my check, it turns out that the power supply is not working and there is no voltage on all the feet.At first, I thought the fuse was burned out due to frequent start, but I took the power off and saw th
Machine Basic configuration: CPU processor This Intel Celeron III 1.2G, Brand 815P motherboard, 512M DDR266 memory, West data 80GB hard drive. In order to play the best performance of the CPU overclocking, in the overclocking process, the BIOS in the CPU core voltage set to 1.5V, each power-on motherboard self-test display CPU voltage of 1.64V, with testing software is still 1.64V. The motherboard version has been upgraded to the latest. After the CPU
1 PrefaceThe modern induction heat treatment technology is widely used because of its high quality, high efficiency, and environmental protection. As the basis of induction heat treatment technology, the IGBT module of the inverter has been commercialized and has successfully produced 10 ~ 100 kHz IGBT inverter power supply with hundreds of kilowatts of power. Pr
