Title:
PERFORMANCE TEST APPARATUS AND TEST METHOD FOR ELECTROMAGNETIC INTERFERENCE NOISE SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2022/183795
Kind Code:
A1
Abstract:
A performance test apparatus and test method for an electromagnetic interference noise separator. The apparatus is composed of a conduction noise separator (1) under test, an in-phase power distributor (2), an inverting power distributor (3), a 50Ω matching load (4) and a dual-port network analyzer (5), which are connected by means of a 50Ω coaxial line, wherein the conduction noise separator (1) under test is provided with two input ports (1-1, 1-2) and output ports (1-3, 1-4), which are used for inputting power source line noise signals and outputting a differential-mode noise component and a common-mode noise component, and the inverting power distributor (3) and the in-phase power distributor (2) are used for simulating a differential-mode signal and a common-mode signal. In addition to being used for a performance test of a conduction noise separator, the test method can also be used for a performance test of a filter; the separation and quantization of a common mode and a differential mode are performed on electromagnetic compatibility disturbance conduction noise during a product test process; and scientific and effective targeted guidance is provided for common-mode and differential-mode filter parameters designed for suppressing conduction noise during an electromagnetic compatibility rectification and optimization process.
