Control circuit and method of electric output modes
First Claim
1. A control circuit of electric output mode for use on a stacked power supply system which has a circuit board to integrate a plurality of power supply devices to output electricity, the circuit board comprising:
- a control circuit includes 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 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 the parallel power supply mode or the backup power supply mode for the power supply devices.

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.

5. A control method of electric output mode for use on a stacked power supply system which has a circuit board to integrate a plurality of power supply devices to output electricity, the circuit board having a control circuit to actuate the power supply devices, the control method of the control circuit comprising the steps of:
-
activating external electricity;
determining electricity output mode;
the control circuit confirming signal source conditions of a switch device before generating an actuation signal to connect the external electricity, entering a parallel power supply mode when a first signal source is detected, entering a backup power supply mode when a second signal source is detected;
confirming whether all of the power supply devices having been connected;
In the parallel power supply mode the control circuit confirming first whether all the power supply devices have been connected, entering the next step if connected;
the control circuit stopping sending the actuation signal and returning to the step of confirming signal source conditions of a switch device;
detecting whether damages occur to the power supply devices;
After having determined the parallel power supply mode or the backup power supply mode to output electricity, the control circuit sending a corresponding actuation signal 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 damages detected;
entering the next step when damages detected; and
activating an alarm device;
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. - View Dependent Claims (6, 7)
