摘　　要：非线性负载不断增加,谐波污染日益严重.利用有源电力滤波器对谐波进行补偿从而抑制谐波的方法越来越成为大家关注的重点.在分析有源电力滤波器存在问题的基础上,提出应用新型滤波用固体同步电压源进行电网谐波滤波的新技术.重点介绍了其工作原理、特点及部分电路设计.实验证明该方案可以作为一种新的电网谐波滤波技术应用于实际,具有受电网阻抗影响小、结构简单、体积小、可靠性高的优点.With the increase in non-linear load, the harmonics pollution has become more and more serious. To counter the problems induced by widely using the nonlinear load, APE （active power filter） is one of the effective solutions to harmonics in power system. This paper presents a new idea of suppressing the harmonics based on the existing solid synchronous voltage harmonics source. And the work principle, the control method, the design of the main circuit and so on are proposed and the experimental results show that this circuit reduced size can be put to use as a new technology of grid rejecting harmonics using solid synchronous, which has the advantages of low grid impedance influence, simple structure, reduced size and greater reliability.
