Abstract
A method for controlling a solid state circuit breaker includes detecting a direction of a current flowing through the solid state circuit breaker, obtaining a breaking current value of the solid state circuit breaker according to the detected direction of the current, obtaining a value of a maximum threshold current to flow through the solid state circuit breaker, obtaining a predicted current value within a next sampling period of a present sampling period of the solid state circuit breaker, comparing the predicted current value with the breaking current value, and upon the predicted current value being greater than the breaking current value, delaying the solid state circuit breaker, and upon the predicted current value being greater than the maximum threshold current value, controlling the solid state circuit breaker to disconnect a circuit in which the solid state circuit breaker resides.
