Function of inverter braking resistance-V & T

by:V&T Technologies     2019-11-15
When the motor or other inductive load driven by the inverter is stopped, it is generally realized by means of energy consumption braking, it is to consume the kinetic energy of the motor and the magnetic energy inside the coil through another energy-consuming element after stopping, thus realizing rapid stop. When the power supply stops, the inverter circuit of the inverter is turned on in reverse direction, and the remaining power is fed back to the DC bus of the inverter, and the voltage on the DC bus will rise accordingly, when it rises to a certain value, the braking resistance of the inverter is put into operation, so that this part of the electric energy is consumed by means of resistance heating, and the voltage on the DC bus is maintained as a normal value.
