1. A xenon lamp power supply, comprising:
an input circuit, including an AC input end and a DC output end and being configured to convert an AC input from the AC input end to a DC output from the DC output end;
a coupling assembly, wherein a first end of the coupling assembly is connected to the DC output end;
an output circuit, including a xenon lamp power supply circuit which is connected to a second end of the coupling assembly, to convert an electric energy from the second end to a strong DC for powering a xenon lamp; and
a control circuit, connected to the first end and a third end of the coupling assembly respectively and configured to control an electric energy of the first end of the coupling assembly to transmit the electric energy to the second end and the third end of the coupling assembly by electromagnetic coupling, wherein the third end of the coupling assembly supplies power to the control circuit;
wherein the output circuit further comprises an auxiliary power supply circuit, wherein the auxiliary power supply circuit is connected to a fourth end of the coupling assembly and is configured to convert an electric energy from the fourth end to a weak DC and output the weak DC.
