A system for managing shunt utilization among multiple power converters sharing a common DC bus is disclosed. Each power converter includes a shunt device, typically one or more power resistors, configured to dissipate power from the DC bus. The power converter is configured according to an initial set of configuration parameters to selectively connect the shunt device to the DC bus. Each power converter monitors the amount of power being dissipated from the DC bus via the shunt device connected to that power converter and determines a utilization rate for the shunt device. As the utilization rate increases, the configuration parameters are modified to less frequently connect the shunt device to the DC bus. As the utilization rate decreases, the configuration parameters are modified to more frequently connect the shunt device to the DC bus.
