作为电力电子系统的 “功率执行核心”，该模块的核心价值是解决中高压场景下 “电能精准调控” 与 “设备安全运行” 的需求，具体功能包括：

 

电能形态转换：实现 AC-DC（整流，将电网交流电转为直流电）、DC-AC（逆变，将直流电转为可调频 / 调压的交流电），为电机、风机等大功率负载提供符合工况的电源；

动态功率调节：通过内置高耐压功率器件（如 IGBT）的高频开关控制，实时调整输出功率，适配负载的动态需求（如电机转速变化、扭矩调整），避免能源浪费；

多层安全保护：集成过流、过压、过热、短路、IGBT 故障保护功能，当系统出现异常（如负载短路、电网电压波动）时，可在毫秒级切断功率回路，保护模块及后端设备；

电磁兼容优化：通过电路拓扑设计与滤波元件，抑制电能转换过程中产生的谐波干扰，符合 GB/T 14549（中国）、EN 61000（欧盟）等电磁兼容标准，避免影响电网及周边设备。

Core Value

As the “power execution core” of power electronic systems, this module addresses two critical needs in medium- and high-voltage applications: precise control of electrical energy and safe operation of equipment.

Key Functions

• Electrical Energy Conversion
  Performs AC–DC rectification (converting grid AC power into DC power) and DC–AC inversion (converting DC power into adjustable-frequency/voltage AC power), delivering power sources that meet the operating requirements of high-power loads such as motors and fans.

• Dynamic Power Regulation
  Utilizes high-frequency switching control with integrated high-voltage power devices (e.g., IGBTs) to adjust output power in real time. This enables adaptation to varying load demands (such as motor speed or torque changes) and minimizes energy waste.

• Multi-Layer Safety Protection
  Incorporates overcurrent, overvoltage, overtemperature, short-circuit, and IGBT fault protections. In the event of anomalies (e.g., load short circuit, grid voltage fluctuation), the power circuit can be disconnected within milliseconds to safeguard both the module and downstream equipment.

• Electromagnetic Compatibility (EMC) Optimization
  Through optimized circuit topology and filtering components, the module suppresses harmonic interference generated during energy conversion. It complies with EMC standards such as GB/T 14549 (China) and EN 61000 (EU) to prevent adverse effects on the power grid and nearby equipment.
