Braking resistor principle: During the process of falling the working frequency, the motor will be in the regenerative braking state. The kinetic energy of the dragging system should be fed back into the DC circuit, so that the DC voltage UD will rise continuously and may even reach dangerous levels. Therefore, the energy regenerated to the DC circuit must be consumed to keep the UD within the allowable range. The braking resistor is used to consume this part of the energy.
