    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 motor control system includes a VFD unit comprising a rectifier circuit having a plurality of phase legs each including thereon an upper switching unit and a lower switching unit, an inverter connected to the rectifier circuit by way of a DC link and having a plurality of switches therein controllable to provide a three-phase AC output power to a load, and a bypass relay unit comprising a bypass relay coupled to each of the phase legs of the rectifier circuit downstream from the lower switching unit. An isolation contactor unit is positioned between the inverter and the load and operable to selectively connect/disconnect the inverter to/from the load. The bypass relay unit is operable in a first and second positions to couple the rectifier circuit to the inverter and to couple the rectifier circuit to a bypass path that bypasses the inverter.

    Abstract: An AC-AC power converter, such as a motor soft starter, includes an input connectable to an AC source with a disconnect switch, an output connectable to an AC load, and phase lines connecting the input and output to transmit power. In-line solid-state switching blocks are connected between line terminals and load terminals of the AC source and AC load, respectively, such that each phase line includes a solid-state switching block connected thereto. Free-wheeling solid-state switching blocks are connected to the load terminals at one end and together at a common connection at another end, such that each phase line includes a free-wheeling solid-state switching block connected thereto. Each of the in-line and free-wheeling solid-state switching blocks comprises a bi-directional switching block that selectively controls current and withstands voltage in both directions. The switching blocks also provide soft-starter functions, variable speed control, and integrated circuit breaker protection capability.
