Description

Technical Field

[0001] This utility model belongs to the field of power electronics and automatic control technology, and specifically relates to an integrated power management device. Background Technology

[0002] With the increasing demand for integrated and high-precision power management in fields such as aerospace and laboratories, traditional distributed power supply modes have shortcomings in terms of multi-channel power control, parameter monitoring, and reliability. There is an urgent need for integrated power management equipment that can provide multi-channel AC / DC power supply, control, and performance parameter monitoring.

[0003] In fields such as aerospace, industrial automation, and laboratory testing, the demand for power management systems is growing. Traditional power management solutions typically use distributed, independent power supply devices, requiring separate deployment of power supplies for multiple devices. This results in low space utilization in laboratories or testing sites, complex wiring, and most power supplies rely on manual adjustment or independent control panels, making it difficult to achieve synchronous control of multiple power supplies. Furthermore, the lack of a unified software management platform makes it impossible to monitor the status of all power supplies in real time. Traditional current / voltage acquisition modules have low sampling rates, making it difficult to capture high-frequency ripples or transient anomalies. They also lack integrated signal analysis functions, requiring external oscilloscopes or power analyzers, which increases costs. Utility Model Content
