Abstract
An exemplary heating ventilation and cooling (HVAC) system includes a multi-phase power input, an AC-DC rectifier connected to a DC-AC inverter via a DC power bus, a multi-phase power output connecting the DC-AC inverter to a fan blower motor, and at least one redundancy power system. The redundancy power system is configured to bypass at least one of the AC-DC rectifier and the DC-AC inverter.
