BRAKING Circuit. On some inverter models, there is an internal braking circuit that can turn on. This circuit will turn on when the DC Bus voltage rises indicating an inrush of current from the motor into the inverter as a motor is slowing down. This will happen at or about 380vdc for a 240vdc inverter, and 760vdc for a 480vdc inverter.
