an energy-storage capacitor;
a first power converter, wherein an output port of the first power converter is coupled to a load, and the first power converter is configured to generate a direct current signal to supply power to the load during a light load interval and a heavy load interval; and
a bidirectional converter coupled between the load and the energy-storage capacitor; wherein
the first power converter is further configured to charge the energy-storage capacitor via the bidirectional converter during at least part of the light load interval; and
the energy-storage capacitor is configured to supply power to the load via the bidirectional converter during the heavy load interval.
