Abstract:
In order to improve the accuracy of junction temperature control,a parameter optimization method for active thermal control of power devices is proposed. An objective function of proportional-integral(PI)parameter optimization is constructed based on the active thermal control principle and the thermal network model of power devices. The objective function is solved by genetic algorithm to obtain the optimal PI parameters. To verify the effectiveness of this method,a single phase full bridge circuit is composed of power MOSFETs,and dynamic current limiting is taken as the means of active thermal control. The active thermal control of power devices is simulated and experimented under different maximum current limits,initial junction temperature and ambient temperature. Results show that the proposed method can improve the accuracy of junction temperature control.
