摘要
针对电磁干扰源(EMI),设计了一种交错并联控制方式的多路输出BUCK变换器。详细介绍了交错并联控制的工作方式,对其进行了时域和频域分析,与同相控制方式进行了比较,并通过Saber仿真软件对其进行了仿真验证。最后完成了一台28 V输入,四路18 V/1.5 A输出的实验样机,测试结果表明,交错并联控制方式可以有效地减小干扰源的1次谐波的幅值,提高基波频率,为实现LOW-EMI变换器提供有效途径。
For the Electro magnetic interference(EMI)noise source,a multiple-output BUCK converter is designed with interleaving parallel control mode which is introduced in detail and analyzed in time domain and frequency domain,as well as compared with the phase control mode,and verified with the theoretical analysis,simulated by Saber simulation software.In the end,a prototype of 28 V input and four 18 V/1.5 A outputs is finished and the test results verify that the interleaving parallel control mode can reduce the amplitude of first harmonic from the noise source,which provide an effective approach to realize the LOW-EMI power regulator.
