EMC

Question: Is there EMC problems with the control driver?

Answer: No, EMC problem is not at severe as the frequency is quite low (160kHz divided to 40kHz for each winding) and since the stator is operating in near resonance, i.e. sine wave. We have done some EMC testing and with the present layout of the driver; it will need some additional decoupling and shielding to pass a standard EMC test. We believe this is doable, but have refrained herefrom since the driver ordinarily is rebuilt to our customers' PCBs. The high voltage is in it self not a problem since all switching is occurring on the primary side.
