Currently, the power system in our country is gradually transitioning from traditional phase-controlled power sources to modular high-frequency switching power supplies for DC power. The working principle of a high-frequency switching power supply rectifier: AC power is connected to the rectifier module, filtered, and then converted to DC through a three-phase full-wave rectifier. The DC is then fed into a high-frequency inverter circuit, converting it to high-frequency AC. After passing through a high-frequency transformer, rectifier bridge, and filter, a stable DC output is produced. This high-frequency switching power supply is mainly composed of high-frequency switching charging modules, centralized systems, and battery packs, among which the charging modules and centralized systems are equipped with built-in microprocessors, featuring high intelligence. Aviation Power
The high-frequency switching power supply rectification module features an integrated microprocessor, serving as the foundation for improving equipment management levels. It ensures that wiring is simplified and installation and debugging are expedited while striving to be as comprehensive as possible in responding to fault signals in DC systems. In addition to directly displaying output current and voltage, as well as various operating conditions of the module on the panel, it can also communicate with the automated network of the power system or the DC section of the substation's transformer maintenance team through the monitoring module. This enables remote monitoring and operation of the module's various functions, achieving the four remote capabilities. 400HZ power supply
The high-frequency switching power supply rectification module features an automatic current balancing function under parallel operation. It is also equipped with overcurrent, overvoltage, and instantaneous short-circuit protection, as well as reliable lightning protection measures, capable of effectively withstanding output short-circuit surges. Additionally, multiple effective measures are taken to prevent interference from high-frequency power and harmonics on the AC grid side. Aviation ground power supply
