Abstract: A stator-less electric motor for an MRI system is provided. The stator-less electric motor includes a body, a rotor rotatable connected to the body, and at least one coil winding disposed on the rotor. The at least one coil winding is arranged so as to rotate the rotor when energized via an electrical current in the presence of a magnetic field generated by a magnet assembly of the MRI system.

Abstract: An uninterruptible power supply (UPS) and methods of operation are provided. The UPS includes a transformer configured to receive power from a utility. The transformer includes a primary winding, a secondary winding, and a tertiary winding. The UPS also includes a rectifier coupled to the secondary winding and an inverter coupled to an output of the rectifier, wherein a connection between the rectifier and the inverter defines a DC link. The inverter is configured to output a first regulated voltage configured to be provided to a load. The UPS further includes a voltage-boost converter coupled to the tertiary winding and is configured to output a second regulated voltage to be combined with the first regulated voltage.

Abstract translation: 提供不间断电源（UPS）和操作方法。 UPS包括被配置为从公用设施接收电力的变压器。 变压器包括初级绕组，次级绕组和三次绕组。 UPS还包括耦合到次级绕组的整流器和耦合到整流器的输出的逆变器，其中整流器和逆变器之间的连接限定了DC链路。 逆变器被配置为输出被配置为提供给负载的第一调节电压。 UPS还包括耦合到第三绕组的升压转换器，并被配置为输出要与第一调节电压组合的第二调节电压。
