Abstract
A multi-stage dynamic braking resistor network () is provided that includes a plurality of dynamic brake resistors () for dissipating, as heat, regenerative energy inputted onto a system bus () by a motor or actuator (), and a plurality of switches () for connecting the dynamic brake resistors () to and from the system bus (), respectively. The multi-stage dynamic braking resistor network () further includes a control circuit () for controlling the switches () such that the dynamic brake resistors () are connected to and from the system bus () on the basis of a predetermined voltage threshold of the system bus and on the basis of a predetermined rotation pattern.
