摘　　要：为了提高一个稳态强磁场实验装置(SHMFF)电源系统中直流有源滤波器的滤波效果,将其纹波电流降低至万分之一,借鉴其他稳态强磁场实验装置中串联调整有源滤波器的优点,提出了一种新型的基于能量回馈和注入补偿的并联型线性调整有源滤波方案。对组成该有源滤波器的电源模块、功率器件模块及其控制系统进行详细分析可知,该有源滤波装置的容量显著降低,且大大提高了装置的效率。实验结果表明,该滤波器能够将纹波电流限制在允许的范围内,具有低功耗、高效率的优点。In order to improve the filtering effect of DC active power filter in the power supply of a steady high magnetic field facility （SHMFF） and to reduce the ripple current of the filter to 1/10 000, a parallel linear adjustment active filter scheme is proposed. The scheme is based on the energy feedback and injection compensation, and it referred to the adjustment active filter of other SHMFFs. Moreover, the active filter power module, power device module, and control system of this active filter are analyzed in detail, and it is found that the active filter＇s capacity is significantly reduced, and its efficiency is greatly improved. Experimental results show that the filter can limit the ripple current in the allowable range with low power consumption and high efficiency.
