Abstract EN
Now electric machines integrate with power electronics to form inseparable systems in lots of applications for high performance.
For such systems, two kinds of nonlinearities, the magnetic nonlinearity of iron core and the circuit nonlinearity caused by power electronics devices, coexist at the same time, which makes simulation time-consuming.
In this paper, the multiloop model combined with FE model of AC-DC synchronous generators, as one example of electric machine with power electronics system, is set up.
FE method is applied for magnetic nonlinearity and variable-step variable-topology simulation method is applied for circuit nonlinearity.
In order to improve the simulation speed, the incomplete Cholesky conjugate gradient (ICCG) method is used to solve the state equation.
However, when power electronics device switches off, the convergence difficulty occurs.
So a straightforward approach to achieve convergence of simulation is proposed.
At last, the simulation results are compared with the experiments.
