Abstract

A control circuit and control method of electric output modes for a stacked power supply system which has a circuit board to integrate a plurality of power supply devices to output electricity. The circuit board has a control circuit to actuate the power supply devices. The control circuit provides a parallel power supply mode and a backup power supply mode, and is connected to a switch device which provides a first signal source and a second signal source corresponding to the parallel power supply mode and the backup power supply mode to enable users to select an actuation signal output from the control circuit to determine the parallel power supply mode or backup power supply mode of the power supply devices.

Claims

1. A control system of electric output mode for use on a stacked electronic power supply system, said stacked electronic power supply system having a circuit board to integrate a plurality of electronic power supply devices to output electricity, the circuit board comprising:

a control circuit having a parallel power supply mode in which all of said electronic power supply devices are operational and a backup power supply mode in which at least one of said electronic power supply devices is not operational and the remaining electronic power supply devices are operational, and is connected to a user operated switch device external to the stacked power supply system which provides a first signal source and a second signal source corresponding respectively to the parallel power supply mode and the backup power supply mode to allow users to select an actuation signal output from the control circuit to determine whether the control circuit operates in the parallel power supply mode or the backup power supply mode, wherein the first signal source is a high potential signal, and the second signal source is a low potential signal;

said control circuit being connected to an external electricity source initially without providing power to said electronic power supply devices, for selectively providing external electricity to said power supply devices only after a mode of the control circuit is selected by a user and if the parallel power supply is selected, confirming whether all power supply devices are connected;

said control circuit being connected to an alarm device to display physical damage conditions of the power supply devices;

said circuit board integrating an electrical output from said plurality of electronic power supply devices to output electricity.

2. A control method of electric output mode for use on a stacked electronic power supply system, said stacked electronic power supply system having a circuit board to integrate a plurality of electronic power supply devices to output electricity, the circuit board having a control circuit to actuate the electronic power supply devices, the control method comprising the steps of:

activating external electricity to provide power to said control circuit without providing power to said electronic power supply devices;

determining electricity output mode by the control circuit by confirming signal source conditions of a user operated switch device external to the stacked power supply system before generating an actuation signal to connect the external electricity to thereafter enter a parallel power supply mode in which all of said electronic power supply devices are operational when a first signal source is detected, or enter a backup power supply mode in which at least one of said electronic power supply devices is not operational and the remaining electronic power supply devices are operational when a second signal source is detected;

confirming whether all of the power supply devices have been connected in the parallel power supply mode, the control circuit confirming first whether all the power supply devices have been connected and entering the next step if connected or the control circuit stopping sending the actuation signal and returning to the step of determining electricity output mode by confirming signal source conditions of a switch device;

detecting whether physical damage has occurred to the power supply devices after having determined the electricity output mode;

the control circuit sending a corresponding actuation signal to selectively provide external electricity to drive the power supply devices, and the power supply devices sending feedback operation signals to the control circuit which determines whether damages have occurred to the power supply devices;

repeating the detection process when no damage is detected; and

activating an alarm device when damage is detected, the control circuit determining damage conditions of the power supply devices according to the operation signals and sending an alarm signal to the alarm device which displays damage messages of the power supply devices and informs users to replace the power supply devices,

said circuit board integrating an electrical output from said plurality of electrical supply devices to output electricity,

wherein the first signal source is a high potential signal, and the second signal source is a low potential signal.
