125v dc power supply

The power ripple index of the DC/DC module is an important parameter. A clean power supply is a prerequisite for the stable operation of the digital circuit and an important guarantee for the parameters of the simulator. To determine the

A simple method to increase AC-DC power supply power loss and keep timeAbstract: In some special applications, the conventional AC-DC switching power supply

Overview With the development of science and technology, power electronic equipment and people's work, life, and the relationship between the increasingly close, and electronic equipment can not be separated from the reliable power supply, so the DC switching power

The typical Ldo power supply itself consumes (vin-vout) *iout, so the larger the two, the greater the power consumption and the lower the efficiency.LDO, switching power supply DC's advantages and disadvantages (2008-11-06-22:40:23) Reprint Tags:

Electronic Circuits Require DC power supply to provide energy. Because the battery cost is high, it is generally only used in low-power portable instruments. Here we will discuss how to convert an AC power supply to a

The adjustment tube of the linear power supply is working in a magnified state, so the heat is generated and the efficiency is low (about 35%). A large heat sink is required, and a large power frequency transformer is also required, the transformer will be larger when multiple voltage outputs are to be made.The adjustment tube of the switch

adjustment generally defines low-level vs at the MV level. As the input voltage changes, the MV level can be increased by ten times (compared with the output voltage ), when the output voltage adjustment transistor is close to the breakdown point, its gain will decrease accordingly. Line adjustment can also implement Ripple Suppression (VIN /? Vout ratio), and should be greater than 60 dB, to avoid AC ripple through the input power line access Linear

Is currently the main direction of power development, smaller, more efficient, more stable ---- High Integration, higher efficiency, and more powerful functions are currently the main development direction of

A Distributed Power Supply System is a large-capacity power supply system composed of several small-Capacity Power Supply Modules. It is a relatively small Power

efficiency of the switching power supply is small, but the voltage and current adjustment rate is discounted compared with the linear power supply. (3) Summary A low dropout regulator is a low-voltage differential linear voltage regulator, which is relative to a traditional linear voltage regulator. Traditional Linear

First, the principle of DC circuit (1) Buck type converter Brief analysis: During the opening of the switching tube s, the current is charged to the capacitance C through the switch tube and inductance. When the switching tube s is off, the filter capacitance C is charged to r, because the inductor current cannot be mutated, through the RC circuit, D discharge Brief calculation: When the switch tube is on, there is Reduction can be obtained inducta

Detailed description of data center Power Supply Mode Electricity for data center equipment, just like gasoline for cars, cars cannot start without oil, and data centers cannot run without electricity, therefore, electricity is the most important thing for Data Center devices. All those who have learned the power base know that electricity is mainly divided into

the efficiency of the switching power supply. It is a hot topic in the international power supply field in the past few decades. For low-voltage and high-current output soft-switch converters, the way to further improve their efficiency is to reduce the switching mode loss. For example, the Synchronous rectification S

The basic function of the power supply in the computer is to convert 220V alternating current into the low-voltage DC power required by the computer, generally it is difficult to see the effect on the performance of the whole machine intuitively. But as a source of power,
