摘要： A charge-controlling system and a method therefor are applicable to a backup power system having a fuel-cell-based power supply and a battery. The charge-controlling system includes a bidirectional converter, a feedback circuit, a voltage controller, a PWM generator, a switch unit and an over-charging protection circuit. The feedback circuit generates a feedback signal corresponding to an output voltage of the bidirectional converter. The voltage controller generates a control voltage according to the feedback signal and a constant voltage, such that the PWM generator generates a PWM signal based on the control voltage. The over-charging protection circuit controls operation of the switch unit according to the feedback signal and a saturation voltage of the battery. When the switch unit electrically connects the bidirectional converter and the PWM generator, the bidirectional converter charges the battery with the power generated by the fuel-cell-based power supply according to the PWM signal.

摘要： The present invention discloses a random controlled fuel cell power module. The random controlled fuel cell power module includes a power module system, a current detection unit, and a random control unit. The power module system is composed of at least two parallel-connected DC/DC converters, for providing the power for a load. The current detection unit detects a load current value of the load. The random control unit reads the load current value and randomly assigns a control mode to activate the DC/DC converters according to the load current value, so that the DC/DC converters can be equally used. Therefore, the failure rate of the DC/DC converters is reduced, the life of the power module system is relatively prolonged, and the stability of the power module system is simultaneously increased.
