| Abstract: | Aiming at the influence of parasitic parameters on the dead time of power MOSFET,based on SIMPLIS simulation software and the characteristics of MOSFET,this paper establishes a simulation analysis model by MOSFET,and studies the relationship between the parasitic parameters of MOSFET and the Miller platform and the turn-off time in the circuit.The piecewise linear model of parasitic capacitance of MOSFET is established.Parameters are compared and analyzed by MATLAB software.Transfer and output characteristics are determined according to the working principle of internal devices.An equivalent model of MOSFET is obtained by image data.The electric circuit of LLC resonant converter is built by MOSFET.The influence rule of parasitic parameters is obtained by simulation experiments under different conditions.A series of simulation training can effectively improve students'simulation practice ability. |
