Abstract: A motor control system for selectively controlling power from a power source to a load includes a PCB structure and a power converter affixed to the PCB structure that is operable to provide a controlled output power to the load. The motor control system also includes a standalone protection and control module mounted onto the at least one PCB structure so as to be electrically coupled therewith, the standalone protection and control module further including a front-end switching unit comprising a plurality of switching devices operable to selectively interrupt and control power flow from the power source to the power converter and to a bypass path that bypasses the power converter and a back-end switching unit positioned downstream from the front-end switching unit and comprising a plurality of switching devices operable to selectively interrupt power flow from the power converter and the bypass path to the load.

Abstract: A compact motor control system for selectively controlling power from a power source to a load includes a motor switching assembly having a solid state contactor with a plurality of solid state switches. The motor switching assembly also includes at least one direct current (DC) link coupled to the solid state contactor and redundant first and second inverters coupled to the at least one DC link. The motor switching assembly further includes a first relay coupled between the solid state contactor and an input of the inverter and a second relay coupled between the solid state contactor and an input of the second inverter. In addition, the motor control system includes a control system programmed to control the motor switching assembly to selectively supply power to the load from the power source.

Abstract: A motor control system includes a motor switching assembly comprising a power converter positioned on a converter path, a first relay positioned on the converter path upstream of the power converter, a second relay positioned on a bypass path that is in parallel with the converter path, and a solid-state switching unit positioned upstream from the converter path and the bypass path. The motor control system also includes a control system that controls operation of the motor switching assembly, with the control system programmed to operate the solid-state switching unit in one of a conducting mode, a non-conducting mode, and a ramping mode, so as to selectively control and condition power flow therethrough. The control system is also programmed to control switching of the first and second relays between open and closed positions to selectively route power along the converter path or the bypass path.
