Abstract
A power supply circuit for a magnetic bearing system comprises a power convertor configured to be electrically connected to an alternating current (AC) power source, an inverter configured to be electrically connected between the power convertor and a motor associated with the HVAC system, and a battery, an input side of the battery electrically connected to a direct current (DC) bus configured between the power convertor and the inverter, and an output side of the battery electrically connected to one or more electromagnetic bearings and a magnetic bearing control drive associated with the motor or the magnetic bearing system, wherein the battery is configured to receive and store a portion of the DC electrical power. The battery is configured to supply the stored electrical power to the electromagnetic bearings and the magnetic bearing control drive in an event of failure of supply of electrical power to the motor.
