Abstract
The utility model discloses an input voltage power failure restarting control circuit of an energy-saving ageing power supply, wherein a PWM (pulse-width modulation) control chip of the energy-saving ageing power supply is SG3525; the input voltage restarting control circuit comprises a triode, a first current-limiting resistor and a second current-limiting resistor, wherein the triode is a PNP (plug-n-play) type triode; the first current-limiting resistor and the current-limiting resistor are respectively connected with a collector electrode and a base electrode of the triode; the other end of the first current-limiting resistor is connected with a seventh foot of SG3525; and the other end of the second current-limiting resistor is connected with the input end of an ageing power supply module. As the PNP type triode is connected at the soft starting end of the ageing power supply, the normal starting can be carried out when the voltage jump is carried out to a single module.
Description
Technical field
The utility model relates to energy-conservation aging field of power supplies, particularly a kind of centrally connected power supply power supply based on GS3525.
Background technology
At present, there is a kind of large-sized DC to become the system power supply of direct current, adopted 100 patterns (each module is a DC/DC conversion passage, the output of the shared system of the output of module) that equal modules makes up.In such system the inside, if each module all uses an accessory power supply to do power supply, the cost height, and energy consumption is also high, and such loss is in the current society that advocates energy-conserving and environment-protective, apparent very waste.At above drawback, people propose the mode of centrally connected power supply, and this mode adopts two block power supply module centrally connected power supply patterns, a main usefulness, and one is standby, has reduced cost and energy consumption when having increased reliability.But under the mode of centrally connected power supply, single module is because accessory power supply is unified the supply, can not control separately, so when the input voltage of certain module changes to " 0V " suddenly from rated voltage, again from " 0V " when changing back to rated voltage, this module is inoperable in fact then.Because existing always, the auxiliary power supply of this module (independent auxiliary electric power supply is arranged unlike those, its energy is supplied with by input and is changed), and the voltage of soft start end also can exist always, can not bleed off (because SG3525 is working always), so even this module has become rated voltage again in input, the output of module is " 0V " in fact.Be that module can not be resumed work again after the power down of module input voltage recovered normally again.
The utility model content
In the power-supply system that overcomes present centrally connected power supply, during for the individual module voltage jump, the deficiency that module can not be resumed work again, the utility model provides a kind of input voltage re-starting control circuit.
The utility model for realizing the technical scheme that its purpose adopts is: a kind of input voltage re-starting control circuit of energy-conservation aging power supply, the pwm chip of described energy-conservation aging power supply is SG3525, comprise the triode and first current-limiting resistance and second current-limiting resistance, described triode is the positive-negative-positive triode, described first current-limiting resistance links to each other with base stage with transistor collector respectively with second current-limiting resistance, the 7th pin of another termination SG3525 of described first current-limiting resistance, another termination of second current-limiting resistance is somebody's turn to do the input of aging power module.
The utility model is owing at the soft start end of aging power supply and connect a positive-negative-positive triode, can normally start when making the individual module voltage jump.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the utility model embodiment 1 circuit theory diagrams.
Embodiment
Embodiment 1, and as shown in Figure 1, present embodiment is the re-starting control circuit of a kind of PWM module when being restarting for the energy-conservation aging power input voltage of centrally connected power supply of SG3525, at the soft start end of aging power supply and connect a positive-negative-positive triode.Physical circuit as shown in Figure 1, a kind of input voltage re-starting control circuit of energy-conservation aging power supply, the pwm chip of described energy-conservation aging power supply is SG3525, control circuit comprises triode Q1 and three electronic components such as the first current-limiting resistance R1 and the second current-limiting resistance R2, wherein triode Q1 is the positive-negative-positive triode, the first current-limiting resistance R1 links to each other with base stage with triode Q1 collector electrode respectively with the second current-limiting resistance R2, the 7th pin of another termination GS3525 of the first current-limiting resistance R1, also be E1+extremely continuous, the input that another termination of the second current-limiting resistance R2 should aging power module.
The course of work of present embodiment is as follows:
When circuit when input is high level, when promptly input being arranged, Q1 ends, and is inoperative.When input voltage drops to " 0V " suddenly because of certain reason, the Q1 action, E1 discharges by Q1, thereby SG3525 is also turn-offed; When importing again from immediately newly-built, Q1 ends again, makes SG3525 recover normal.Even thereby to have realized importing in the time of can not controlling power supply, power supply also can be followed having or not of power supply of input and switch work.
Claims (1)
1. the input voltage re-starting control circuit of an energy-conservation aging power supply, the pwm chip model of described energy-conservation aging power supply is GS3525, it is characterized in that: comprise triode (Q1), first current-limiting resistance (R1) and second current-limiting resistance (R2), described triode (Q1) is the positive-negative-positive triode, described first current-limiting resistance (R1) links to each other with base stage with triode (Q1) collector electrode respectively with second current-limiting resistance (R2), the 7th pin of another termination GS3525 of described first current-limiting resistance (R1), another termination of second current-limiting resistance (R2) is somebody's turn to do the input of aging power module.
