Inductive load switch-off energy
dissipation
Energy stored in load inductance:
While demagnetising load inductance, the energy
dissipated in PROFET is
with an approximate solution for R L > 0 Ω:
The device is not suitable for permanent PWM with
inductive loads if active clamping occurs every cycle.
