Modular high frequency switching power supply
Modular high frequency switching power supply
Abstract: Hubei British Special Electric Co., Ltd. for customers to supply modular high-frequency switching power supply prices, manufacturers, which home good, how much money, sales, manufacturers, procurement, products are sold to Guangdong, Xinjiang, Jiangsu, Beijing, Shanghai, Shandong, Sichuan, Gansu and other regions.

Modular high frequency switching power supply

Overview
Using IGBT PWM technology to transform electric energy, it has the advantages of intelligence, modularization, digitalization, network "Sihua", high frequency, high-efficiency, high reliability, high power density, high power factor "five high" characteristics.

Widely used in new materials preparation, high-end manufacturing, energy saving and environmental protection, data center, plasma torch, sewage treatment, robot charging and other fields。

 

Working principle

Three-phase (single-phase) AC input is filtered by AC-DC Rectifier, from the insulated gate transistor (IG BT) or MOSFET composed of the frequency-DC converter circuit or other forms of circuit, by High-frequency (about 10-40khz) transformation and regulation, and then by high efficiency rectification filter to be suitable for the user's required DC power supply.
The control system adopts All-digital DSP control, integrates auxiliary power circuit, input and output sampling circuit, PWM generation, communication interface circuit, protection circuit and so on, and has the advantages of control precision and high stability/corresponding speed, good anti-interference performance, perfect protection system and rich communication interface.
