1、Experimental Study on Six-phase Motor Co-simulation And EMI FilterIntroduction Six-phase motor is widely used in industrial productionand it is increasingly researched and applied in electricalcars, ship propulsion(艦船推進), aerospace etc. Computer simulation is a simple way to solve complexproblems. I

2、t provides a significant tool to examine thecorrectness of the circuit design.Software UsednMaxwell establish motor modelnSimplorer design control circuitnMATLAB (simulink) use the sub-library simpowersystems to make electrical simulation to generate svpwm waveMotor model in Maxwell (cut surface fig

3、ure, 48 stator slots, 38 rotor slots)Generate svpwm waveform circuit in MATLABThe total co-simulation circuit in SimplorerSimulationnSimulation stop time at 100ms (5 periods), the minimum step 10us.nThe computer runs for about 240 hours to complete it.nResults as follows:Motor Voltage( first phase)F

4、FT analysis (first phase)Motor Current( first phase)FFT analysis( first phase)Motor Torque(轉(zhuǎn)矩)Svpwm waveform Coreloss(鐵芯損耗)Wireloss(線圈損耗)ConclusionnThe results are basically satisfactory.nMy boss gives me this task in last November and I have finished it in the beginning of this semester. Now what I

5、 am doing is the EMI filter. Thats what I want to talk about next.EMI Filter nElectrical 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 electrom

6、agnetic compatibility(電磁兼容).nIn this project, my work is to find a circuit to separate common mode signal and differential mode signal(共差模信號).nMain IdeaOperating Frequency: 150kHz 30MHz High-pass filter(高通濾波器)(to filter signals below 150kHz)High-frequency transformer（高頻變壓器）(separate common mode sign

7、al and differential mode signal)Test DataTransformer normal operating frequency: 300Hz 50kHzHigh-pass filter cutoff frequency: 4.78kHzInput Signal: 10 Vp-pAnalysisnHigh-pass filter output satisfies the design requirements.nThe transformer output is inconsistent with expectations. Normal operating frequency of the transformer cant meet the needs.SolutionnSearch for transformer meet requirements: can stably work from 150kHz to 30M
