Fig. 2 is that the electric power of electric power enable circuits one embodiment of uninterruptible power supply provider of the present invention enables to control the framework circuit diagram.
Embodiment
Relate to detailed description of the present invention and technology contents, now just cooperate graphic being described as follows:
See also shown in Figure 1ly, be the basic power supply circuits configuration diagram of one embodiment of the invention, as shown in the figure: the present invention is that a kind of electric power of uninterruptible power supply provider enables (enable) circuit, is applied in the computer system.This computer system includes the uninterruptible power supply provider that a motherboard (motherboard) 50 and is electrically connected at this motherboard 50.This motherboard 50 includes a CPU (central processing unit, CPU) and other electronic components and circuit layout at least.This uninterruptible power supply provider also carries out signal communicating with this motherboard 50 except the needed electric power of these motherboard 50 normal operations is provided.The electric power enable circuits of uninterruptible power supply provider of the present invention include one under normal circumstances output power give the main power supply system 10 and of this motherboard 50 at the normal output power and replace it redundant electric power system 20 of electric power to this motherboard is provided of this main power supply system 10.
In present embodiment, this main power supply system 10 includes power factor correction function unit 12, a transformer 13, a pulse width control unit 14, a switch element 15 and the rectification output unit 16 that a rectification filtering unit 11, that connects external power source 40 connects this rectification filtering unit 11.Behind interchange external power this rectification filtering unit 11 of process and this power factor correction function unit 12 of these external power source 40 outputs, this power factor correction function unit 12 utilizes an inner transformation power level to adjust power factor and the voltage of this external power.This pulse width control unit 14 determines the work period of this switch element 15, uses the coil current of adjusting by this transformer 13.At last, produce a power conversion 101 via this rectification output unit 16, and this power conversion 101 is sent to this motherboard 50.This power conversion 101 is a direct current electric power.This redundant electric power system 20 includes the charhing unit 21 of the power conversion 101 of obtaining these main electric power system 10 conversion outputs, and at least one this charhing unit 21 of accepting is filled with this power conversion 101 and it is saved as the energy-storage module 22 of a redundancy electric power 201.This redundant electric power system 20 is exported this redundancy electric power 201 to this motherboard 50 when this main power supply system 10 can't be exported this power conversion 101.In present embodiment, this energy-storage module 22 is a rechargeable battery.
See also shown in Figure 2ly, for the electric power of one embodiment of the invention enables to control the framework circuit diagram, as shown in the figure: in the present invention, this main power supply system 10 is electrically connected at an electric power with this redundant electric power system 20 and enables control circuit 30.This main power supply system 10 produces one first electric power good signal 102 for 101 times at this power conversion of aforementioned normal output and enables control circuit 30 to this electric power.This first electric power good signal 102 that this electric power enables these main power supply system 10 outputs of control circuit 30 receptions produces second a corresponding electric power good signal 301 with simulation.This electric power enables control circuit 30 and includes this second electric power good signal of output 301 normal power supply states to this motherboard 50, and one receives the redundancy electric power 201 of these redundant electric power system 20 outputs and continues this second electric power good signal 301 redundant power supply states to this motherboard 50 of output.
In the present invention, when the user started this computer system, this motherboard 50 was exported first an electric power starting signal 501 to this main power supply system 10 and this electric power and is enabled control circuit 30.These main power supply system 10 these electric power starting signal 501 rear delay one first setting-up times (such as 2 seconds) of reception are exported this first electric power good signal 102 and are enabled control circuit 30 to this electric power.This electric power enables control circuit 30 behind this first electric power good signal 102 that receives these main power supply system 10 outputs under the normal power supply state, export one second electric power good signal 301 to this motherboard 50 according to these the first electric power good signal 102 synchronous modulation, this second electric power good signal 301 possesses the waveform identical with this first electric power good signal 201.On the other hand, this electric power enables control circuit 30 and receives this electric power starting signal 501, start first this redundant electric power system 20, and certainly receive these electric power starting signal 501 rear delay one second setting-up times (such as 2 seconds) and export this second electric power good signal 301 to this motherboard 50.When this main power supply system 10 can't normally provide this power conversion 101 to this circuit board 50, this electric power enables 30 of control circuits and is in a redundant power supply state, receives the redundancy electric power 201 of this redundant electric power system 20 outputs and continues this second electric power good signal 301 of output to this motherboard 50.
When the user determined to close this computer system, this computer system then stopped to export an electric power starting signal 501 to this main power supply system 10 and this electric power and enables control circuit 30.Lack the electric power starting signal 501 that receives from these motherboard 50 outputs in case this electric power enables control circuit 30, will not export this second electric power good signal 301 to this motherboard 50, and make this computer system carry out shutdown programm.
In sum, the electric power enable circuits of uninterruptible power supply provider of the present invention, when main power supply system output has the power conversion of normal working voltage, export one first electric power good signal and enable control circuit to this electric power, this electric power enables control circuit and further simulates one second corresponding electric power good signal of output to a motherboard, makes it carry out follow-up boot program; When this main power supply system can't be exported normal conversion electric power, then change by this redundant electric power system one redundancy electric power is provided, this electric power enables control circuit when detecting the redundancy electric power of this redundant electric power system, also then continue this second electric power good signal of output to this motherboard, still can make this motherboard finish start.So, whether uninterruptible power supply provider no matter main electric power system can normal operation, and this motherboard can both obtain the electric power good signal to finish follow-up boot program.
Below the present invention is described in detail, yet the above person only is a preferred embodiment of the present invention, when not limiting scope of the invention process.Be that all equalizations of doing according to claim scope of the present invention change and modify etc., all should still belong in the patent covering scope of the present invention.
