nissan leaf simulation

PSIMbeginner25

Hello, can you please help me?

I would like to simulate in psim a three-phase inverter with PWM control, a 3L NPC inverter and a 5L ANPC inverter included one by one in a circuit simulating the operation of a Nissan Leaf motor replaced by an asynchronous motor of specific parameters (Rs = 0. 45 Ω, Lls = 0.0018 H, Rr = 0.6 Ω, Llr = 0.0018 H, Lm = 0.07 H, Poles = 4, J = 0.015 kg-m²). I have created the 3 types of inverters but I don't know how to link them in the schematic. At the end I want to compare the waveforms of the currents on phases, voltage, motor speed and estimated losses to highlight the usefulness of the inverters.

Hi,

When a simulation contains more than one machine block, a coupling block must be used. Otherwise, an error message will typically occur.

If you have three inverters and want to connect an induction motor (IM) to compare voltages and currents:

1. First setup: Connect the IM to the three-phase inverter, run the simulation, and save the results. Disable the other two inverters during this step.
2. Second setup: Disable the three-phase inverter with IM, enable the three-level NPC inverter with IM, run the simulation, and save the results.
3. Third setup: Disable the three-level NPC with IM, enable the five-level NPC with IM, run the simulation, and save the results.
4. Final step: Merge the saved results from the three simulations to compare the performance.

Thank you,
