1. A power supply system, comprising:
a power source connected between a first node and a second node for applying an input voltage;
a first circuit, connected between the first node and a second circuit; and configured to suppress oscillation caused by load variation of a load circuit that is connected between the first node and the second circuit, and to supply power to the load circuit when the power source is temporarily off;
the second circuit, having a first port connected to the first circuit, a second port connected to the load circuit, and a third port connected to the second node; and configured to charge the first circuit and supply power to the load circuit; and
a third circuit, connected between the first circuit and the load circuit; and configured to suppress a current flowing into the second circuit.
