中文摘要:
      电磁兼容是空间产品设计和测试的一项重要内容,滤波器是抑制电磁干扰和提高可靠性及技术指标的有效手段。文章简要介绍了电源变换器母线滤波器的特点,对滤波器型式和参数的优化选择原理进行了分析计算,重点论述了非匹配阻抗滤波器的设计方法,在详细的理论分析基础上得出了准确的非匹配谐振频率点和有效的补偿方法。文章通过具体案例详细介绍了整个设计过程,并对设计结果进行了最坏情况分析和仿真验证。结果证明:本方法能够有效抑制非匹配谐振,最大程度地降低了对元件参数的精度要求,在任何非匹配阻抗(内阻和负载电阻)情况下,也就是母线电压大范围变化或任何功率等级情况下可保证滤波器的峰值系数小于1.2。
英文摘要:
      EMC is an main term of design and test for space power converter, filter is a effective method for suppressing EMI and advancing reliability as well as technical parameters. The filter characteristics that be connected between main bus and dc-dc converter are introduced in briefly, the principle for selecting parameters and type of filter in optimistically is analyzed . design methods of the filter with non- matched impedance is be described in emphatically, an formula for compensating frequency response is be obtain on the basis of detail theory analysis. The design process especially as inductor is described in detail by an application case. Simulating result verify that the design method can suppress resonance very effectively and reduce precision requirement for parts parameters, it can be confirmed that the peaking factor is less 1.2 in any non-match situation including source resistance and load , in other words, the filter adapt in any bus voltage variable range and any power levels.
