For the analysis of a power electronic circuit designs that need to be like in reality, we need a more accurate model. In power electronics, MOSFET transistors are the most usual. In what follows we will post the list spice models for transistors like IRF540, IRFZ44, IRF810, etc. Level 3 empirical models.
To simulate real life due to parasitic inductances will include TO220 or TO204 lead inductances as follows:
For TO-204 (modified TO-3) source = 12.5nH drain = 5.0nH
For TO-220 source = 7.5nH drain = 3.5-4.5nH
For TO-220 source = 7.5nH drain = 3.5-4.5nH
Because we introduced lead inductances, voltage spikes due to di/dt will be modeled. This is important because we will see if a MOSFET will exceed the Safe Operating Area, and Maximum Drain Voltage.
The models will work for Orcad or Ltspice with very minor modifications or not.
In this model LEVEL 3 the following effects are modeled:
-transfer curves in forward operation
-gate drive characterization of impedance and switching delay for loads
- Rds on resistance variation with respect of Vgs
- reverse mode operation of body diode
