1、Experimental Study on Six-phase Motor Co-simulation And EMI Filter,Introduction,Six-phase motor is widely used in industrial productionand it is increasingly researched and applied in electricalcars,ship propulsion(舰船推进),aerospace etc.Computer simulation is a simple way to solve complexproblems.It p
2、rovides a significant tool to examine thecorrectness of the circuit design.,Software Used,Maxwell establish motor modelSimplorer design control circuitMATLAB(simulink)use the sub-library simpowersystems to make electrical simulation to generate svpwm wave,Motor model in Maxwell,(cut surface figure,4
3、8 stator slots,38 rotor slots),Generate svpwm waveform circuit in MATLAB,The total co-simulation circuit in Simplorer,Simulation,Simulation stop time at 100ms(5 periods),the minimum step 10us.The computer runs for about 240 hours to complete it.Results as follows:,Motor Voltage(first phase),FFT anal
4、ysis(first phase),Motor Current(first phase),FFT analysis(first phase),Motor Torque(转矩),Svpwm waveform,Coreloss(铁芯损耗),Wireloss(线圈损耗),Conclusion,The results are basically satisfactory.My boss gives me this task in last November and I have finished it in the beginning of this semester.Now what I am do
5、ing is the EMI filter.Thats what I want to talk about next.,EMI Filter,Electrical equipments are widely used in our daily life.They bring great convenience to our life and also make our electromagnetic environment more and more complex.EMI filter is a method to solve the problem of electromagnetic c
6、ompatibility(电磁兼容).In this project,my work is to find a circuit to separate common mode signal and differential mode signal(共差模信号).,Main Idea,Operating Frequency:150kHz 30MHz,High-pass filter(高通滤波器)(to filter signals below 150kHz),High-frequency transformer（高频变压器）(separate common mode signal and dif
7、ferential mode signal),Test Data,Transformer normal operating frequency:300Hz 50kHz,High-pass filter cutoff frequency:4.78kHz,Input Signal:10 Vp-p,Analysis,High-pass filter output satisfies the design requirements.The transformer output is inconsistent with expectations.Normal operating frequency of the transformer cant meet the needs.,Solution,Search for transformer meet requirements:can stably work from 150kHz to 30MHz.Find another way to separate common mode signal and differential mode signal without the transformer.,Thank You!,
