摘　　要：针对传统Delta逆变器式交流稳压电源所含工频变压器体积重量大、噪声高,以及市电受污染、用户端小功率用电设备受市电质量影响大等问题,利用串联谐振电流型高频链逆变电源在高质量输出电压、全程软开关等方面的优势与Delta逆变技术在改善市电、提高用户负载端电能质量上的优越性,提出将串联谐振高频链结合Delta逆变技术用于小功率稳压电源;然后根据该稳压电源的工作原理与控制方法,给出了其对市电电压波动和所含谐波补偿的公式推导;最后在Matlab/Simulink环境下搭建仿真实验平台.仿真结果表明,该稳压电源不仅减小了设备体积和重量,提高了系统效率,还可对市电电压波动和所含谐波进行补偿,实现了在小功率场合下用户负载端电能的高质量输出.The frequency transformer of the traditional Delta inverter AC regulated power supply(PS) is bulky, heavy and noisy. In addition, the electric supply is polluted and the low power equipment of the user's side is greatly affected by the quality of the mains. By using the advantages of the series-resonant-current-typed high frequency chain inverter PS in the high-quality output voltage and the all range soft-switching and other aspects,as well as the superiority of Delta inverter technology in improving the electric supply, increasing the quality of electric energy of the user's load side, this paper proposes that the series resonant high-frequency chain combined with Delta inverter technology is used for small power PS. Meanwhile, according to the working principle and control method of the regulated PS, the paper gives the formula derivation of the mains voltage fluctuation and the harmonic compensation. Finally, the simulation experiment platform is built in the Matlab/Simulink environment.Simulation results show that the regulated PS not only reduces the size and weight of the equipment, and improves the system efficiency, but also compensates the mains voltage fluctuation and the contained harmonics, and consequently realizes the high quality electric energy output of the user's load side in the case of small power.
