| Abstract |
The goal of this research is to reduce the common mode current in inverter system. To reach the goal, it is important to understand the behavior of common mode current precisely in the inverter circuits. Recently, computer simulation is widely used for this issue according to create good simulation model for individual electric component in used inverter system. The simulation results/accuracies are strongly depend on the modeling level/accuracy as widely known. In this paper we create the system simulation model for core design and motor model with grounded impedance as well. In this simulation, the key point is soft magnetized core modeling can be used in system simulation. Also this paper illustrates how to utilize the system simulation for inverter and motor drive system. This technique is verified by simulations and experiments. |
