摘要
针对微网中电能转换效率低等问题,文章提出了一种输出电压稳定、电能转换效率高的分布式能源系统。该系统由直流/直流(Direct Current/Direct Current,DC/DC)模块和逆变模块组成,采用STM32为主控芯片并结合正弦交流调制技术进行调制,从而优化各模块,实现高效率转化。测试结果表明,该系统输出电压稳定,转化效率高等特点,能较好地提高充电效率。
The paper proposes a distributed energy system with stable output voltage and high power conversion efficiency to address the problems of low power conversion efficiency in microgrid.The system consists of a DC/DC(Direct Current/Direct Current)module and an inverter module,which is modulated by STM32 as the main control chip and combined with sinusoidal AC modulation technology,so as to optimize each module and achieve high efficiency conversion.The test results show that the system has stable output voltage and high conversion efficiency,which can improve the charging efficiency.
