Technical field
The utility model relates to a kind of communication power supply of ultralow stand-by power consumption.Relate in particular to and be applicable to that power-supply system output has the communication power supply of storage battery as system load.
Background technology
At present, large power supply generally adopts two-stage: prime Active Power Factor Correction pfc circuit, back level transformer isolation DC-DC power conversion circuit, do the one-level auxiliary power circuit in Active Power Factor Correction pfc circuit or the output of transformer isolation DC-DC power transforming main circuit in addition and come to provide operating voltage to the control circuit and the logical circuit of prime Active Power Factor Correction pfc circuit, back level transformer isolation DC-DC power transforming main circuit.Because under no-load condition, prime Active Power Factor Correction pfc circuit, back level transformer isolation DC-DC power transforming main circuit, auxiliary power circuit still consume certain power.
In order to solve the stand-by power consumption problem, general way has three kinds at present: a kind of is the input of cutting away power supply when system standby, but the shortcoming of this way is to need independently standby accessory power supply, be the two accessory power supplys of duplex feeding, so also need the EMC problem of otherwise address standby accessory power supply, increased the cost of system undoubtedly, system is numerous and diverse, is exactly the two accessory power supply standby theory diagrams of duplex feeding as shown in Figure 1.
Second kind is that the input of complete machine accessory power supply is got from the output of Active Power Factor Correction pfc circuit, the Active Power Factor Correction pfc circuit is not worked, turn off back level transformer isolation DC-DC power transforming main circuit simultaneously, this moment, the input of accessory power supply only was the commutating voltage of alternating current, closed power factor correction pfc circuit, DC-DC schematic block circuit diagram with regard to single accessory power supply as shown in Figure 2.
The third is that the complete machine accessory power supply is got from back level transformer isolation DC-DC power transforming main circuit output, the main output of transformer isolation DC-DC power transforming main circuit separates with the input of accessory power supply, cut off transformer isolation DC-DC power transforming main circuit master output during standby, PFC is quit work, although this scheme has been cut away the main output of DC-DC power transforming main circuit, but the DC-DC main circuit is still in work, so bigger idling consumption is still arranged, be that single accessory power supply closes the power factor correction pfc circuit as shown in Figure 3, DC-DC master's output principle block diagram.
Two kinds of backs are than first kind of standby accessory power supply independently, thereby circuit is simple than first kind, and the while also need not be handled independently problems such as standby power EMC.But their accessory power supply is still in work, thereby necessarily palpus clump electrical network draw energy, the problems such as harmonic wave, power factor and EMC when needing to solve standby.
Summary of the invention
The purpose of this utility model has been to overcome the shortcoming that prior art still needs draw from electrical network energy when the standby, a kind of communication power supply of ultralow stand-by power consumption is disclosed, cleverly from transformer isolation DC-DC power transforming main circuit output loading---storage battery comes the power management MCU circuit supply to system, thereby do not draw energy, problems such as the harmonic wave of power supply and power factor when efficiently solving standby simultaneously during standby from electrical network.
A kind of communication power supply of ultralow stand-by power consumption comprises EMI circuit module, rectification circuit module, power factor correction PFC module, transformer isolation DC-DC Power Conversion module and output loading storage battery that order links to each other; And control described power factor correction PFC module power factor correction PFC control circuit D2, the described transformer isolation DC-DC Power Conversion module of control transformer isolation DC-DC Power Conversion control circuit D3 be connected the output loading storage battery and control the power management MCU circuit module of described power work; Alternating current is imported described EMI circuit module; Also comprise the auxiliary power circuit module, isolated controlling optocoupler module D4 and the accessory power supply control circuit module D1 that connect power factor correction PFC control circuit D2 and transformer isolation DC-DC Power Conversion control circuit D3 simultaneously, described power management MCU circuit module is controlled described accessory power supply control circuit module D1 by described isolated controlling optocoupler module D4 and is quit work when receiving standby command.
The utility model and the comparative analysis of related art scheme: need not self-contained circuit work during this patent standby, really realize ultralow stand-by power consumption.These patents all are cut-off parts circuit as required when standby, still there is partial circuit to draw energy from electrical network, there is fundamental difference to adopt method and apparatus described in the utility model with this patent power management MCU circuit from the power taking of load storage battery, compared with prior art, owing to draw energy from electrical network hardly during standby, realize ultralow stand-by power consumption, thereby saved the energy, improved power grid quality.
