Abstract
A power system (100) includes power conversion apparatus (110) coupled to load apparatus (120) having at least one load circuit (122,124). The power conversion apparatus includes: a first input (102) for receiving an AC signal; a second input (104) for receiving a DC signal; and a first number of power supply circuits (112) each including an AC conversion circuit (210, 240, 250) for generating an output signal based on the AC signal; a revert circuit (270) coupled to the AC conversion circuit for generating the output signal based on the DC signal, the revert circuit including a battery charger (274), wherein each of the battery chargers is coupled in common at the second input and is configured with a corresponding predetermined capacity that causes at least a portion of the DC signal to be provided by at least a portion of the battery chargers.
