Û LL /U n Relative peak line-to-line voltage
(du/dt)/U n Relative du/dt value
Note: Û LL and du/dt values are approximately 20% higher with resistor braking.

Additional note for sine filters

A sine filter also protects the motor insulation system. The peak phase-to-phase voltage
with a sine filter is approximately 1.5 · U
