| Abstract |
Hard switching PWM inverter drives produce high conducted electromagnetic interferences (EMI). The EMI
emission mainly depends on the cable length, the rated power of the induction motor, the de link voltage of the inverter
and the switching time of the IGBT. The commonly use of EMI filters can not reduce the EM! noise below the limits
in each case. The filter damping can be reduced due to the interaction between filter and drive system. Another method
to limit the EMI spectrum especially in the high frequency range is the increase of switching time. A simple model is
proposed to simulate the conducted interferences at every operation point of the drive system. The paper presents
simulation and experimental investigations. |
