Abstract
The disclosure relates to the field of power electronic technology, and discloses an electrothermal co-simulation method, system and terminal for the power electronic system, comprising the following steps: carrying out electrical simulation on the power semiconductor device and its power circuit, and junction temperature simulation on the power semiconductor device; acquiring real-time electrical parameters in the electrical simulation process; suspending the electrical simulation in a steady state until the steady state of the electrical simulation is changed; and calculating the junction temperature according to the real-time electrical parameters and in combination with the real-time loss of the power semiconductor device in the electrical simulation process. The disclosure dynamically controls the electrical simulation state, thereby reducing the calculation amount in the simulation process and achieving the purpose of accelerating the simulation convergence.
