<p>A power system is disclosed. The power system comprises a plurality of power supply units, a voltage sharing bus, and a current sharing bus. The sharing bus is used to transmit a sharing voltage, and the current sharing bus is used to transmit a first current reference value. Each of the power supply units comprises: a power converter, a feed-forward control (FFC) circuit, and a feedback control (FBC) circuit. The feed-forward control circuit is used to generate a second current reference value according to a difference between an input voltage of the power converter and the sharing voltage. The feedback control circuit is used to generate a current compensation value according to the second current reference value and the first current reference value. The power converter can adjusts the output current thereof in accordance with the current compensation value.</p> |
