Embodiment
See also Fig. 1, Figure 1 shows that the utility model high efficiency alternating electromotive force stores and the circuit block diagram of electric supply installation.The utility model comprises an ac high-voltage constant-current charge circuit 10, and it connects the power supply A (being generally civil power) of 220 volts of input single-phase 110 volts or two-phases, as the charging source of battery pack 20.The utility model can wireless extension connect battery pack 20, battery pack 20 and the utility model line 21.The utility model also provides the network port, and the networking signal is sent to user B to show the utility model state and to use the power state in zone via the INTERNET networking.Fig. 2 then is an enforcement circuit flow chart of the present utility model.
Power supply host computer system 30 of the present utility model can be one to multiple group, and power supply host computer system 30 is connected with battery pack 20, and the utility model is different from other products only for single group design, and compared to other products, the utility model can provide the electric power output of great number.CPU treatment system 40 is connected 41 with ac high-voltage constant-current charge circuit 10, and be connected 42 with power supply host computer system 30, and be connected 43 with load circuit 50, CPU treatment system 40 can be detected immediately from above-mentioned ac high-voltage constant-current charge circuit 10, power supply host computer system 30, and with being connected signal and calculating of load circuit 50, but send control command then and make the utility model normality supply moment and the full output services that carry, and can be when load current be excessive with in the load (group) 60 the most the load of power consumption close, and when short circuit or pulse are excessive powered-down main frame 30.
Can include low-and high-frequency detecting circuit, loop circuit for detecting, electronic wave form compensating circuit, low-and high-frequency compensating circuit, load circuit for detecting, phase inversion integration system in the above-mentioned again one to multiple group power supply host computer system 30, link up interface, interface output and little processing computing system, constitute main circuit of the present utility model.
Ac high-voltage constant-current charge circuit 10 can comprise certain voltage high voltage direct current charger; unfixed point expansion type independent battery charging system input; relay tip formula delay protection circuit; microprocessor electronics Host Protection system; the unusual checking circuit of high-low voltage power source, charging circuit Electronic Protection control circuit detects battery pack paradoxical discharge system and (detects battery charging and discharging; and manual operation circuit independently working).Above circuit is to be connected 11 with CPU microprocessing systems 40, and is connected to battery pack 20 respectively, makes the utility model become high efficiency output main frame.
This host computer system is at connect different moment starting current that causes between the various different loads 60, CPU microprocessing systems 40 will launch instant detecting with aforesaid connection line, open parallel connection power supply host computer system 30 at pulse current, the work of expansion power-supply circuit, finish loading demand, electronic wave form compensating circuit and current limliting compensating circuit will be filled to waveform cut-off region and saturation region with full type waveform simultaneously, to promote the waveform supply power, can't bear the jumping machine that power pulse is produced to overcome general uninterrupted power supply electric storage device to load 60, saturated even the embarrassed shape that burns.Native system is different from general uninterrupted power supply electric storage device and adopts PWM correction type square-wave waveform to make modulation (pulse wave width modulation waveform circuit), that is native system not with the waveform width as revising index, but the cut-off region and the saturation region of waveform separated, and the in addition complete waveform output of full signal (electronic impulse charging modes), this is different for this power supply output system with general uninterrupted power supply electric storage device, also is to overcome the improvement place of problem in the past.
What this must special one carries be, the battery supply electric power that the present utility model is required, in addition instant computing of reason CPU microprocessing systems 40, detecting load output pulse current, various load, starting current, so the utility model can make full use of battery power (can infinitely expand) to the power supply low state, be low to moderate can't load the time when battery supply simultaneously, the utility model will send one and clearly instruct to load circuit 50, with with the load of power consumption suggestion shutdown the most among the load group, this be generally do not cut off the power supply electric storage device the function that can't provide.
The utility model is when power supply short circuit or during heavy duty, and CPU microprocessing systems 40 will judge that whether output current is short circuit, or heavy duty causes power supply fast rise and loss with instant computing.Be judged as one of said two devices situation; CPU microprocessing systems 40 is about to aforesaid connection line and launches the loop; the shutdown protection is also closed the phase inversion output circuit, and drive circuit shuts down simultaneously, and protective circuit is opened; unusual circuit detecting system is opened; the signal electronic loop is opened, and by integrating, links up interface unlatching transmission signal and notifies the user; carry out 30 shutdown of power supply host computer system simultaneously, open isolator cut-out battery and prevent short circuit or heavy duty with being connected of main frame and load.Native system is different from the traditional protection mode, and its protective device is to utilize the traditional relay tripping circuit as protective circuit.But because of its tripping overlong time, circuit receives the surge voltage of being fed back by battery pack already, and general uninterrupted power supply electric storage device can't be closed system one by one, and then causes short circuit to burn, and causes danger, even causes battery pack 20 short circuits blast.The utility model is improved design with this situation, replaces traditional relay road protective circuit with the Electronic Protection loop, is the motherboard protective circuit system of a new-type design.
Ac high-voltage constant-current charge circuit design 10 of the present utility model is a multisection type, and a regulating and controlling voltage office is wherein arranged in the input voltage stage casing, can accept 110 volts to the 275 volts voltages that do not wait.This design is to design at different users's needs, the supply voltage A in for example same civil power market must not be same magnitude of voltage, general uninterrupted power supply electric storage device can't adapt to more than one magnitude of voltage, more can't on-the-spotly revise machine voltage, cause manufacturer must develop two or more circuits, and causing fluctuation of price not good, the circuit utilization rate such as can't popularize at problem.The utility model was both improved at this phenomenon, insert different inputs when this product can be imported via the scene and just can be suitable for 110 volts of markets, also can be suitable for 100 volts of markets, more can be used for 200 volts and 220 volts of markets, strengthen the applicability and the value of product greatly.
The utility model and design have battery impulse charging electronic loop system (as Fig. 2), because the charging principle mode of general uninterrupted power supply electric storage device is a double frequency type height voltage charging method, the charging of this kind mode can cause the charging temperature of battery to raise, produce memory effect, reduce the accumulate capacity, reduce battery life, make battery greatly reduce service time, increase the battery use cost on foot.The utility model adopts the electronic impulse charging modes, and its principle is the variable pressure charging, detects the electric current and voltage of battery simultaneously, supplies with the required electric energy of battery with the charged state of variable pressure shifting current.
