A switching power supply brand
1. Schneider Electric (China) Limited, began in 1920 in France, the global energy efficiency management experts, the leading brand in the field of power distribution equipment for the country's energy and infrastructure/data centers and networks/buildings and residential markets to provide a total solution. 19th century, Schneider Electric is engaged in the iron and steel industry, heavy machinery industry, shipbuilding industry; 20th century, Schneider Electric is engaged in the iron and steel industry, heavy machinery industry, ships and boats. construction industry; in the 20th century, in the power and automation management industry.
2. Menzies AG is a leading global technology company, founded in 1847, with operations in more than 200 countries worldwide, focusing on electrification, automation and digitalization. As one of the world's largest suppliers of energy-efficient and resource-saving technologies, Siemens holds leading positions in offshore wind turbine construction, combined-cycle power generation turbines, transmission solutions, infrastructure solutions, industrial automation, drives and software solutions, as well as medical imaging equipment and laboratory diagnostics.
3. Delta was founded in Shanghai in 1992 by Zhongda Dentsu, and has maintained a high average annual growth rate of 27% since it opened for business, providing industrial-grade users with efficient and reliable power, video, automation and energy management solutions. The company has a leading market share in communication power supplies, and is also a leading manufacturer of video display and industrial automation solutions.
The role of switching power supply
1. Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, electric power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, LCD monitors, LED lamps and lanterns, communications equipment, audio-visual products, security monitoring, LED lighting, computer chassis, LED strip, computer chassis, and so on. LED strip, computer chassis, digital products and instrumentation and other fields.
2. Switching power supply process is quite easy to understand, in the linear power supply, so that the power transistors work in linear mode, with linear power supply is different, PWM switching power supply is to let the power transistors work in the state of conduction and shutdown, in both states, added to the power transistors on the volt-ampere product is very small (in the conduction, the voltage is low, the current is large; shutdown, high voltage, current is small)/power device. Current is small) / power devices on the volt-ampere product is the power semiconductor devices on the losses incurred.
There are a lot of people for switching power supply is not understood, so we have to understand, then what are the brands of switching power supply and what is its role, I want to see the above small introduction we all understand it.
