1. A solid-state circuit breaker, comprising:
three electronic switch modules, wherein an input of one of the three electronic switch modules is configured to be connected to a phase of an AC power source, respectively, and an output of one of the three electronic switch modules is configured to be connected to a phase of a load, respectively; and
an energy-absorbing apparatus comprising:
three first diode branches, wherein each of the three first diode branches comprises two diodes whose anodes are connected to each other forming a first diode branch midpoint, each of the three first diode branches are respectively connected between respective two phases of three phase lines, and three of the first diode branch midpoints are connected to each other;
three second diode branches, wherein each of the three second diode branches comprises two diodes whose cathodes are connected to each other forming the second diode branch midpoint, each of the three second diode branches are respectively connected between respective two phases of the three phase lines, and three of the second diode branch midpoints are connected to each other;
a transient diode unit connected between the first diode branch midpoint and the second diode branch midpoint.
