A DC output power converter or DC switch device that includes methods and apparatus to reverse the current in the connected load, thereby draining the load's energy until the voltage in the load is brought to a (near) zero potential and held there.

Method and apparatus to remove energy from DC loads

An AC-DC power converter controls an external upstream switching device, which supplies it power to be converted. Power conversion is initiated when an external signal requests power be converted or when a program within the AC-DC power converter detects the need for power conversion. When this occurs, the AC-DC power converter signals the external switching device, which is upstream of the AC-DC power converter to turn on, thereby supplying the power to be converted to the AC-DC power converter.

Method and apparatus for protection of AC-DC power converters

A power and safety control hub, integrating fault tolerant power disconnect control, software monitoring of disconnect and multi-voltage power distribution and disconnect with non-hazardous power control, EMI filtering and multi-circuit current protection in a single unit, coordinating shutdown of connected mechanical drives, commanding them to come to a controlled stop before safety power is disconnected. The hub may also integrates segmented hazardous power control and automatically discharge energy sources within connected mechanical drives at the time of safety power disconnect of hazardous power. The hub may also include internal self-protection that automatically forces a control safety power disconnect (after warning the host) if the unit should approach its maximum operating temperature, or if a cooling fan stops.
