System composition (components)

According to functional units, the system consists of the following components, and the basic functions of each component are as follows:

High frequency switch rectifier module

High frequency rectification module completedAC/DCTransform and implement the basic functions of the system.

● AC power distribution

The three-phase AC input power is distributed to various high-frequency rectification modules through power distribution, and its extended function is to achieve automatic switching of two AC input power sources.

● DC power supply

Distribute the DC bus voltage to each DC output circuit through distribution.

Silicon Chain Voltage Regulating Unit

Reduce the output voltage of the rectifier module and the battery voltage to a stable range of control voltage output.

● Monitoring unit device

Manage the entire system, implement the human-machine dialogue window, mainly manage battery charging, and remotely control the system backend. Through monitoring devices, various analog signals of AC, DC, and expansion quantities, as well as various switch signals, are collected, analyzed, and processed, with sound and light alarm information.
