A Behavior Electrical Model of the MOSFET Using Matlab/Simulink

MATLAB/SIMULINK is a general software used in various domains. The ’sIMPOWER,' ’sIMSCAPE' and ’sIMULINK' libraries are dedicated to the electrical engineering domain. These libraries' power electronic devices models do not reflect their effective functioning. In this work, we are interested in the power Metal Oxide Semiconductor Field Effect Transistor “MOSFET” component. The proposed model is an electrical equivalent circuit composed of linear and nonlinear electrical elements (resistors, capacitances, controlled current source). It is implemented as a SIMSCAPE circuit in the graphical tool of MATLAB. The model parameters are extracted from the datasheet manufacturer for an example of the MOSFET component (MOSFET IRF740 10A/400V). Furthermore, the results are validated using the manufacturer’s data and measurements
