Product introduction

Basic parameters: SPTU240R2 ABB DCS power controller

Due to its high efficiency, safety, reliability and easy system upgrade, BMP is widely used in industrial automation, relay protection, distribution network automation, rail transit, automotive electronics, aerospace and other high reliability and high performance fields. The correct and reasonable selection of DC/DC module power supply can save the trouble of power supply design and debugging, and focus on their own professional fields, which can not only improve the reliability and design level of the overall system, but more importantly, shorten the development cycle of the entire product.

[Module power supply technology development trend]

In order to meet the market requirements for the continuous improvement of power performance, DC/DC module power supplies have been to high efficiency, high power density, high frequency, digital, wide input voltage range, low voltage and high current, low noise. The direction of miniaturization, high reliability, miniaturization and standardization

Since 1996, Lucent launched the half brick power module, the module power supply in nearly 20 years has been rapid development, the author began to engage in the module power supply work from 2003, witnessed the rapid development process of the module power supply, taking the 1/4 brick communication module power supply as an example, from the first time the author opened the module power supply development in 2003. The 1/4 brick module has an efficiency of 87% and a power of 60W, and by 2020, the efficiency of the 1/4 brick module power supply will reach 98% efficiency and 1200W power. Improved efficiency by 11% and power density by 20 times.

High efficiency: With the development of semiconductor technology and process, new power devices with low on-impedance and low switching loss continue to emerge, as well as the maturity and application of soft switching technology, which promotes the further improvement of the efficiency of module power supplies;

High power density and miniaturization: With the development and maturity of planar transformers, planar inductance technology, multi-layer thick PCB process and technology, and wide band gap semiconductor material GaN, the development of high-frequency and miniaturization of module power supplies has been promoted. Especially the development of GaN power devices, because of its good high-frequency switching and low loss advantages, will further significantly promote the power density and miniaturization of module power supplies, at the same time, thanks to the integration of active devices, magnetic integration, buried resistance, buried capacity and other passive device integration technology, 3D integrated packaging technology and heat dissipation technology development, The high power density and miniaturization of module power supplies will continue to develop;

Intelligent: With the development and development of digital power management chips, the digital control power supply has promoted the digital development of module power supply, because of its flexible control mode, structured modular design, accurate precision control and adjustment, excellent dynamic response performance and strong noise response and detection characteristics. The digital control and intelligent communication monitoring of module power supply will be an inevitable trend. Especially in the medium and high power module power supply and dynamic intermediate bus power supply architecture system will be widely used;

High reliability: The module power supply on the market is mainly used in the fields of communication, power, rail transit, aerospace and military industry, etc. The reliability and stability of the module power supply are put forward extremely high requirements in related fields. With the improvement of the integration of active and passive devices and the maturity of digital control chips, the number of module power supply devices is reduced. At the same time, with the improvement of efficiency and the development of heat dissipation technology, as well as the progress of the module power supply production and assembly process, the reliability of the module power supply will be greatly promoted.
