摘要
采用IPM(Intelligent Power Module智能功率模块)和MCU(Micro Control Unit微控制器)作为主要部件研制的SPWM中频电源系统,具有系统结构简单,控制灵活的优点。由于中频电源通常应用于对电磁兼容性要求较高的场合,因此,对系统电磁兼容性的改进做了阐述。
The SPWM intermediate frequency power system is based on IPM and MCU can be controlled flexibly and has simple structure. This kind of power supply is normally used in some special area with strict EMC （electromagnetic compatibility） conditions. The paper therefore sets forth more effective measures to improve EMC.
