The difference between switching power supply and modular power supply

The modular power supply is a power supply that can be directly mounted on a printed circuit board, and is characterized by an application specific integrated circuit (ASIC), a digital signal processor (DSP), a microprocessor, a memory, and a field programmable gate array (FPGA). ) and other digital or analog loads provide power. In general, such modules are called point-of-load (POL) power supply systems or point-of-use power supply systems (PUPS). Because of the many advantages of modular structure, module power supply is widely used in switching equipment, access equipment, mobile communications, microwave communications, optical communications, routers and other communications fields and automotive electronics, aerospace and so on.

 Switching power supply is a kind of power supply that uses modern power electronics technology to control the ratio of time when the switch is turned on and off, and maintains a stable output voltage. The switching power supply is generally composed of a pulse width modulation (PWM) control IC and a MOSFET. Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial equipment, communications equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating.

 Nanjing Pengtu Power Co., Ltd. is located at No. 381, Pagang Street, Jiangning District, Nanjing. The company was incorporated in 2007. It is a company specializing in the development, design, production, sales and service of module power supply and power module. The company has hired a group of senior power supply engineers from China Aerospace Group and China Electronics Technology Group, and cooperated with well-known professors and senior engineers from various universities to rely on the cutting-edge technology of scientific research personnel to carefully create application solutions for power products.

 The company not only passed the IS09001-2008 quality system certification, IS014000 quality environmental protection system, but also the electromagnetic compatibility of some products passed the test of the “Jiangsu Institute of Metrology” and other authoritative departments. The product safety and electrical performance are in full compliance with the Ministry of Information Industry "YD/T731", "YD/T731-2000 high frequency switching rectifier standard", and some products have passed UL and CE demonstration.

 Since its establishment, the company has been based on honesty, adhered to science and technology as the guide, and backed by technology, and constantly developed a variety of new high-tech power supplies. At present, it has a number of national patents and the company's "Pengtu" brand. All kinds of power sources have been widely used in railway, military, aerospace, electric power, communications, automatic control, instrumentation, solar photovoltaic, vehicle equipment, ships, major scientific research. Institutions and other fields. The company not only has many well-known domestic customers, but also sells its products to Southeast Asia, Europe and America, and is well received by customers.

 The company will always bear in mind the "quality first, service first" corporate philosophy, to provide users with the most convenient "one-stop" service, with a pragmatic, innovative, refinement of the entrepreneurial spirit, accelerate the company's technological innovation, product development At the same time, we will return to our customers and friends with better products, more meticulous service and better results.
