Appl. No.:

17/173070

Inventors:

- Charlotte NC, US
Mustansir Kheraluwala - Lake Zurich IL, US
Eric A. Carter - Monroe WI, US

International Classification:

H02M 5/458
H02M 1/08

Abstract:

A system comprises a first 3-phase rectifier having a positive DC lead and a negative DC lead and a second 3-phase rectifier having a positive DC lead and a negative DC lead. The system also includes a 4-phase, 3-level inverter connected to the first and second 3-phase rectifiers. A method comprises receiving variable frequency, 3-phase power from a first generator, receiving variable frequency, 3-phase power from a second generator, rectifying the variable frequency, 3-phase power from each of the first and second generators into DC power. And inverting the DC power into 4-phase, constant frequency power for powering a load.

Abstract:

A cooling arrangement for a motor assembly includes a motor operably connected to a load. Also included is a motor controller disposed adjacent to, and fluidly coupled to, the motor, the motor controller disposed within a housing enclosing a cooling fluid for immersion of a plurality of motor controller components. Further included is a duct arrangement configured to route a cooling flow to a location proximate the housing of the motor controller for cooling therealong.
