Abstract
The present disclosure relates to an electrical apparatus comprising: an AC power module including a rectifier system; a DC bus configured to electrically couple the AC power module to a core power module including at least one DC electrical component; a pre-charge circuit; and a control system. The control system is configured to: responsive to a pre-charge initiation signal, perform a pre-charging procedure for pre-charging the DC bus, the pre-charging procedure including: activating the pre-charge circuit to provide a pre-charging current to the DC bus; monitoring a voltage on the DC bus; and responsive to a determination that the monitored voltage on the DC bus has reached a pre-charging threshold, perform a run procedure including: deactivating the pre-charge circuit; and electrically coupling the AC power module to an external AC power supply via an AC bus.
