Abstract
A method of detecting forward and reverse connection of a three-phase motor is disclosed, including: turning on a first solid-state switch pair and a second solid-state switch pair into conduction for a predetermined period of time so that current can flow between a power supply and the three-phase motor; detecting output current of a solid-state motor starter; and determining the forward and reverse connection state of the three-phase motor based on the output current of the solid-state motor starter, in a case that currents exist at a first output terminal and a second output terminal, it is determined that the three-phase motor is in the forward connection state, and in a case that currents exist at the first output terminal and a third output terminal, it is determined that the three-phase motor is in the reverse connection state. Furthermore, a solid-state motor starter is disclosed.
