Zusammenfassung:	A power management system for an elevator system. A power management system for an elevator system includes a power converter having three input terminals, two of the three input terminals coupled to a main power source for supplying single-phase AC power to the power management system, the power converter configured to convert the AC power from the main power source into DC power on a common DC bus, a secondary power source for supplying DC power to the common DC bus, a power inverter configured to invert the DC power on the common DC bus into AC output power for driving an electric motor of the elevator system, and a dynamic braking resistor which is coupled between a third input terminal among the three input terminals of the three-phase power converter and the common DC bus.
