If other external inductive loads L are connected to the PROFET,

additional elements like D are necessary.

Energy stored in load inductance:

EL = 1/2·L·I

While demagnetizing load inductance, the energy

dissipated in PROFET is

EAS= Ebb + EL - ER=

 VON(CL)·iL(t) dt,

with an approximate solution for RL  0 :

EAS=
