I want to design the loss calculation model of three phase inverter and loss calculation of the motor using the FEM Parameterized PMSM

조회 수: 11 (최근 30일)
I am designing the three phase inverter having both the loss calculation of the inverter and motor.
While simulating i am getting an error.
Error compiling Simscape network for model PMSM_MOSFET_2.
Caused by:
  • Frequency and time simulation is not applicable because sinusoidal expressions are not used by any other equations and have been eliminated.
  • Check variable intrm_sf_mf__2.
  • Check variable intrm_sf_mf__3.

Frequency-and-time equation formulation is intended for systems with a single nominal frequency. It is not possible to simulate switching devices such as MOSFETs. When designing the electric drive and power inverter you should set the 'Equation formulation' to 'Time' in the Solver Configuration block.

Thanks Professor, but after making the solver configuration block to "Time". I am getting this error....
An error occurred while running the simulation and the simulation was terminated
Caused by:
Thanks

  • ['PMSM_MOSFET_2/Solver Configuration']: At time 0.000300, one or more assertions are triggered. See causes for specific information.
  • In divide, the denominator must be nonzero. The assertion comes from: Block path: PMSM_MOSFET_2/FEM-Parameterized PMSMAssert location: o (location information is protected)
