Description
Technical field
The present invention relates to a kind of programmable power supply output system, and in particular to the programmable power supply output mould of fixed cycle output
Block.
Background technology
In existing programmable power supply output system, a kind of DC voltage of fixation is only supported to input, when needs change electricity
, it is necessary to which external potential device is changed to the voltage of input during pressure, DC voltage can be changed, changed so as to input
DC voltage after change, and can not fed back in the prior art, the output system of whole programmable power supply can not be real
When understand output data, voltage is adjusted, is inconvenient.
Programmable power supply output system in the present invention can be realized multiple under conditions of+28V fixes DC voltage input
The voltage source output of other magnitudes of voltage of species, and portion voltage can set the fixed cycle to export.All setting outputs
Voltage can be rearranged into the initial value of+28V outputs after test completion.
The content of the invention
The technical problems to be solved by the invention are under conditions of fixed DC voltage input, realize multiple species its
The voltage source output of his magnitude of voltage, and portion voltage can set the fixed cycle to export.The voltage of all setting outputs is complete
The initial value of output can be reset after into test, and it is an object of the present invention to provide the programmable power supply output module of fixed cycle output, solution
The problem of certainly above-mentioned.
The present invention is achieved through the following technical solutions：

Fixed voltage source exports, and after 8 groups of voltage sources export each group all concatenated a resistance and a Schottky diode, and
8 groups of power supplys are all shorted together output after Schottky diode.Its operation principle is as follows：
For example one group of+18V power supply is exported, and can also be by returning to+28V power supplies by key control：
Under most initial state, this equipment acquiescence is+28V outputs, and other 7 groups of power supplys are completely in closed mode.When
User key-press operation is exported with+18V power supplys, after now MCU have received key command, is first turned on the power supply of+18V outputs
Enabled, the power supply for simultaneously closing off+28V outputs enables, and in the process, due to 8 groups all after Schottky diode
Power supply is shorted together, may be a certain if the enabled control between+28V power supplys and+18V power supplys is not connected
Within instantaneous time, output conflict between two kinds of power supplys be present, it is possible to which the power supply exported as+28V can pour in down a chimney the electricity to+18V
Source is got on, and it is exactly to pour in down a chimney for elimination power supply and specially design now to increase Schottky diode.
The breakdown reverse voltage that Schottky diode is chosen is at least above maximum output voltage value 36.5V, it is contemplated that overshoot
Need to retain surplus etc. factor, it should it is safer much larger than the reverse breakdown threshold value, for example choose reversely hitting for 40V and the above
The Schottky diode of voltage is worn, further, since the power module needs to power to whole system, power is more than 20W, then choosing
Electric current that the Schottky diode selected passes through (being calculated according to minimum 10V output voltages) needs 2A, and power supply is in diode in calculating
Interior thermal losses, it is actually needed the electric current that selection passes through and selects 2.5A and above model preferably, the selection of this power module can pass through
3A electric currents, reverse breakdown reach 50V Schottky diode.
