Micro-electromechanical system based electric motor starter

摘要

A motor starter (200) is provided. The motor starter includes micro-electromechanical system switching circuitry (202). The system may further include solid state switching circuitry (204) coupled in a parallel circuit with the electromechanical switching circuitry, and a controller (208) coupled to the electromechanical switching circuitry and the solid state switching circuitry. The controller may be configured to perform selective switching of a load current from a motor connected to the motor starter. The switching may be performed between the electromechanical switching circuitry and the solid state switching circuitry in response to a load current condition appropriate to an operational capability of a respective one of the switching circuitries.
