1. A system, comprising:
a solid-state circuit breaker configured to couple between a power supply and an electrical load;
one or more sensors configured to measure one or more properties associated with the solid-state circuit breaker, the electrical load, the power supply, or any combination thereof;
a control system configured to communicatively couple to the one or more sensors, wherein the control system is configured to:
receive a first set of data from the one or more sensors, wherein the first set of data is received while the solid-state circuit breaker is open;
send a first signal to the solid-state circuit breaker based on the first set of data, wherein the first signal is configured to cause the solid-state circuit breaker to:
turn on a first semiconductor device associated with a first pole in the solid-state circuit breaker at a first firing angle; and
turn on a second semiconductor device associated with a second pole in the solid-state circuit breaker at a second firing angle different from the first firing angle;
receive a second set of data from the one or more sensors after the first signal is sent to the solid-state circuit breaker; and
send a second signal to the solid-state circuit breaker based on the second set of data, wherein the second signal is configured to cause the solid-state circuit breaker to turn off the first semiconductor device and the second semiconductor device.
