Generally, an electrical motor or other inductive load adopts dynamic braking to reach a halt. That is to say, it employs an additional dissipative cell to consume the kinetic energy and magnetic energy to realize fast brake. When the power supply is cut off, the inverter would send the remaining kinetic energy to DC bus. The voltage of DC bus will thus increase. When the voltage is up to a certain value, the braking resistor will come into use and consume the energy through resistance heating. The voltage on the DC bus will then be reduced to a normal value.
