1. A power supply system, comprising a first power supply apparatus, a second power supply apparatus, and a bus tie switch unit, wherein
the first power supply apparatus comprises:
a first solid-state transformer, configured to convert a first alternating current into a first direct current;
a first direct current/direct current converter, coupled to the first solid-state transformer, and configured to convert the first direct current into a second direct current;
a first energy storage component, coupled to the first direct current/direct current converter, and configured to perform energy storage on the second direct current;
a first switch unit, coupled to the first direct current/direct current converter and a second direct current/direct current converter; and
the second direct current/direct current converter configured to convert the second direct current into a third direct current, wherein the third direct current supplies power to a load; and
the second power supply apparatus comprises:
a second solid-state transformer, configured to convert a second alternating current into a fourth direct current;
a third direct current/direct current converter, coupled to the second solid-state transformer, and configured to convert the fourth direct current into a fifth direct current;
a second energy storage component, coupled to the third direct current/direct current converter, and configured to perform energy storage on the fifth direct current;
a second switch unit, coupled to the third direct current/direct current converter and a fourth direct current/direct current converter; and
the fourth direct current/direct current converter configured to convert the fifth direct current into a sixth direct current, wherein the sixth direct current supplies power to the load; wherein
two terminals of the bus tie switch unit are respectively coupled to the first switch unit and the second switch unit.
