Classification: CPC H | IPC H

Claim 6:
7. A method for controlling a solid state circuit breaker, comprising:
detecting a direction of a current flowing through the solid state circuit breaker, wherein the solid state circuit breaker is at a load end of a power grid bus in a direct current (DC) power grid;
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 maximum threshold current value upon the detected direction of the current being a direction from a load end of the solid state circuit breaker to a power supply end of 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.
