Abstract:
A power supply for an HVAC/R system is configured to provide back-up power functionality for situations when the main source of power fails. The power supply includes a DC power bus which receives power from the main source of power as well as a back up source. When the main source fails the back up source provides power to the DC power bus. Connected to the DC power bus is a variable frequency drive power supply (VFD). The VFD is configured to provide power to the components of the HVAC/R system based on power received from the DC power bus.
