| Resumo: |
Accuracy in semiconductor electronic components varies according to some parameters. Among them, the temperature stands out causing changes in their behavior. In the case of MOSFETs, we have change in the current that goes through the component, as well as in the value of its transconductance. These variations may have great influence on the control in systems where the MOSFETs drive the actuators of the control mesh. The objective of this work is to model a drive drive, or bridge H, for a position control system of a DC motor. The drive is composed of four MOSFETs that act as keys and the model considers the temperature variation of the same during its operation. To model the system, the Modelica language was used because of its innumerable advantages in the modeling of complex systems. Results of the simulations demonstrate the behavior of the DC motor and the MOSFETs being subjected to a square wave signal. |
