1. A power system, comprising:
a power input terminal, configured to receive a bus voltage;
a sense terminal, configured to receive a sense voltage indicative of the bus voltage; and
a bi-directional converter, having a first terminal coupled to the power input terminal, and a second terminal;
wherein when the sense voltage decreases to reach or to be lower than a reference voltage, the bi-directional converter is adapted to be configured to operate in a release mode to provide a release voltage at the first terminal, and wherein a voltage value of the bus voltage at a moment when the sense voltage decreases to reach the reference voltage is a transition voltage threshold, and wherein the release voltage varies when the transition voltage threshold varies.
