V
inductive load
If other external inductive loads L are connected to the PROFET,
additional elements like D are necessary.
Inductive Load switch-off energy
dissipation
Energy stored in load inductance:
While demagnetizing load inductance, the energy
dissipated in PROFET is
with an approximate solution for R
