Abstract: Systems and methods for soft starting a motor (40) using solid-state switching devices are disclosed. The system (10) includes a soft starting switch (53) that is made of a plurality of solid-state switches (62, 63). The system (10) also includes a controller (86) that is programmed to regulate currents and voltages delivered to the motor (40) during a start-up operation of the motor by cycling the solid-state switches (62, 63) ON and OFF during the start-up operation.
