Hello Community,
I generally work on 3D simulation tools associated with domains such as Powertrain NVH studies and I am new to Matlab-Simulink tools.
Now I am exploring the electrical/electronics domain (beginner) to get some initial data that will be required for further NVH studies.
I have made a 3-Phase Inverter with Pulse Width Modulation (PWM) circuit with help of tutorials online.
Currently I am facing this issue, where the output current extracted from the 3 Phase Inverter is not having the same magnitude(values) in
3 phases, How to correct the Matlab-simulink model regarding this issue?
Inputs given to the model,
DC Voltage source – 400 V
and Reference Sine wave blocks – Frequency 50Hz and Phase difference of 120 for 3 phases (Amplitude 1)
and carrier wave (Sawtooth generator) – Frequency 10,000 Hz (Amplitude 1)
The Load – 3-Phase Parallel RLC Branch – Only Resistor type is used with 1 Ohm resistance

Note: Regarding the grounding, two approaches I have tried – Grounding the load (RLC) and grounding the Inverter 6-switches loop (both have same results)
Thank you in advance for all the support and helpHello Community,
