Embodiment
Fig. 2 is the calcspar according to the decentralized power supply supply of the utility model one embodiment, and this decentralized power supply supply is applied to LCD TV, but not as limit.Please refer to Fig. 2, decentralized power supply supply 2 comprises electromagnetic interface filter 21, AC to DC converter (it comprises bridge rectifier 22 and PFC 23), main power source transducer 24, standby power transducer 25, switching circuit 26, solar panels 27, charging converter 28, rechargeable battery 29, substitute electric power transducer 30 and asymmetrical circuit element 31 and 32.Decentralized power supply supply 2 receives the AC mains source VAC of representative value 90～264Vrms, and be converted into main power source VM1 and the VM2 of representative value 24V and 12V, and be converted into the standby power VSB of representative value 5V by standby power transducer 25 by main power source transducer 24.Wherein, main power source VM1 powers and is converted into high-voltage ac power to light back light (as CCFL) to inverter, and main power source VM2 powers to loudspeaker, audio-visual control and total system control, and standby power VSB then powers to MCU.
In addition, standby power VSB can also be provided by the photoelectric conversion device that solar panels 27, charging converter 28, rechargeable battery 29 and substitute electric power transducer 30 are constituted.Solar panels 27 can be arranged on the LCD TV shell to receive light extraneous as that the sun or electric light etc. provides, also can be arranged on the light that leaks out when the inner liquid crystal panel of LCD TV rear tapping is lighted work with reception from back light.Solar panels 27 are converted to direct current by opto-electronic conversion with the light that is received, the modulation by charging converter 28 and the control and to rechargeable battery 29 chargings again of this direct current.Whether 30 of substitute electric power transducers are enough and receive electric power starting signal PS_ON or power-off signal PS_OFF determines whether action according to energy stored on the rechargeable battery 29.If 30 actions of substitute electric power transducer, then substitute electric power transducer 30 can be converted to the electric energy of rechargeable battery 29 standby power VSB and be provided to MCU, and standby power transducer 25 will be failure to actuate at this moment; Otherwise if substitute electric power transducer 30 is failure to actuate, then standby power transducer 25 must move and provide standby power VSB to MCU.Therefore, both have only standby power transducer 25 and substitute electric power transducer 30 meeting to move standby power VSB is provided at one time, therefore both outputs must add asymmetrical circuit element 31 and 32 respectively, cause unnecessary power loss or cause circuit to damage to some extent to prevent that power supply from pouring in down a chimney.In this example, asymmetrical circuit element 31 and 32 is a diode.
When power supply unit 2 receives electric power starting signal PS_ON, the LCD TV operate as normal, because the data volume that MCU need handle is huge, the energy of consumption is higher, therefore provide standby power VSB to MCU by standby power transducer 25, and substitute electric power transducer 30 must be controlled it and is failure to actuate.This moment is because back light (as CCFL) has been lighted work, the solar panels 27 that are arranged on the inner liquid crystal panel of LCD TV rear tapping can receive the light that it leaks, after by opto-electronic conversion the light that is received being converted to direct current, again by 29 chargings of 28 pairs of rechargeable batteries of charging converter.And whenever the solar panels 27 that are arranged on the LCD TV shell charge as long as the external world has light can pass through 28 pairs of rechargeable batteries of charging converter 29.
When power supply unit 2 receives power-off signal PS_OFF, LCD TV enters standby mode, main power source VM1 and VM2 because no longer moving, main power source transducer 24 are not provided this moment, back light (as CCFL) is closed, make the solar panels 27 that are arranged on the inner liquid crystal panel of LCD TV rear tapping can not get energy, therefore can only come by 29 chargings of 28 pairs of rechargeable batteries of charging converter by the extraneous light of solar panels 27 receptions that is arranged on the LCD TV shell.If it is enough that power supply unit 2 detects on the rechargeable battery 29 energy stored, then start 30 actions of substitute electric power transducer, energy stored conversion on the rechargeable battery 29 is provided standby power VSB so that MCU to be provided required power, and standby power transducer 25 must be controlled it and is failure to actuate.But, if it is not enough that power supply unit 2 detects on the rechargeable battery 29 energy stored, then still start standby power transducer 25 action, provide standby power VSB so that MCU to be provided required power, and substitute electric power transducer 30 must be controlled it and is failure to actuate by standby power transducer 25.
So, when power supply unit 2 receives that energy stored is enough on power-off signal PS_OFF (being that LCD TV enters standby mode) and the rechargeable battery 29, provide standby power VSB to MCU by 30 actions of substitute electric power transducer, and not action of standby power transducer 25, the therefore only loss of remaining electromagnetic interface filter 21, bridge rectifier 22 and PFC 23 passive devices of the power loss on the whole loop; Moreover, because the capacitor of PFC 23 rear ends does not provide load energy, therefore the situation of voltage drop can not appear, so can be in string crest value voltage always, for whole input, because pressure drop and electric current are quite little, its standby mode power loss will be less than 0.1W.
