Control of soft starter of electric machine using power electronic switching device

Systems and methods for soft start of an electric machine (40) using a solid state switching device are disclosed. The system (10) includes a soft start switch (53) composed of a plurality of solid state switches (62, 63). The system (10) also includes a controller (86) programmed to regulate the current and voltage delivered to the electric machine (40) during a start-up operation by cyclically turning on and off the solid state switches (62, 63) during the start-up operation of the electric machine. 本发明公开了用于使用固态开关设备来使电机(40)软启动的系统和方法。该系统(10)包括由多个固态开关(62,63)构成的软启动开关(53)。该系统(10)还包括控制器(86)，该控制器被编程为通过在电机的启动操作期间使固态开关(62,63)循环导通和关断，来调节在启动操作期间递送到电机(40)的电流和电压。
