作為電力電子系統(tǒng)的 “功率執(zhí)行核心”，該模塊的核心價值是解決中高壓場景下 “電能精準調(diào)控” 與 “設(shè)備安全運行” 的需求，具體功能包括：
電能形態(tài)轉(zhuǎn)換：實現(xiàn) AC-DC（整流，將電網(wǎng)交流電轉(zhuǎn)為直流電）、DC-AC（逆變，將直流電轉(zhuǎn)為可調(diào)頻 / 調(diào)壓的交流電），為電機、風(fēng)機等大功率負載提供符合工況的電源；
動態(tài)功率調(diào)節(jié)：通過內(nèi)置高耐壓功率器件（如 IGBT）的高頻開關(guān)控制，實時調(diào)整輸出功率，適配負載的動態(tài)需求（如電機轉(zhuǎn)速變化、扭矩調(diào)整），避免能源浪費；
多層安全保護：集成過流、過壓、過熱、短路、IGBT 故障保護功能，當系統(tǒng)出現(xiàn)異常（如負載短路、電網(wǎng)電壓波動）時，可在毫秒級切斷功率回路，保護模塊及后端設(shè)備；
電磁兼容優(yōu)化：通過電路拓撲設(shè)計與濾波元件，抑制電能轉(zhuǎn)換過程中產(chǎn)生的諧波干擾，符合 GB/T 14549（中國）、EN 61000（歐盟）等電磁兼容標準，避免影響電網(wǎng)及周邊設(shè)備。
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.
