Description
Technical field
The present invention relates to electronic technology field, particularly relate to the plug-and-play circuit of a kind of changer.
Background technology
Hot plug i.e. warm swap, it is allowed to user in the case of not cutting system power supply into and out system
Assembly, is not result in the system failure, thus improves the recovery capability of system, extended capability etc..Work as system
When assembly is specially changer, the outfan meeting access system dc bus of changer when insertion system, and
It is generally of electric capacity of voltage regulation at changer its outfan internal, therefore in the case of not cutting system power supply,
Changer inserts electrified system moment and can produce bigger dash current, at transducer side adapter 01 be
Between system side-connector 02, arcing occurs, even damage changer.
In prior art, the connection circuit between changer and transducer side adapter 01 is as it is shown in figure 1, become
The setting pin 011 of one output end vo of parallel operation+connection transducer side adapter 01；Current limiting switch and current limliting
A branch road, another output end vo of changer-pass through is constituted with output switch parallel connection after resistance R series connection
This branch road connects the setting pin 012 of transducer side adapter 01；The input Vin of changer connects changer
The setting pin 013 of side-connector 01；When transducer side adapter 01 and system side adapter 02 connect,
Setting pin 011 and 012 in transducer side adapter 01 connection system side-connector 02 respectively connects system
The setting pin 021 and 022 of system dc bus, setting pin 013 connection system in transducer side adapter 01
Side-connector 02 connects the setting pin 023 of changer input power.When carrying out changer heat and inserting, current limliting
Switch Guan Bi, output switch disconnect, and system dc bus is changer by current limiting switch and current-limiting resistance R
Internal electric capacity of voltage regulation charging, can avoid temporary impact by current-limiting resistance R, controls to become after a period of time
Parallel operation is started working, and controls current limiting switch disconnection, output switch Guan Bi, and changer output energy is to being
System dc bus.
But, due to the existence of the internal electric capacity of voltage regulation of changer, arcing problem not only appears in changer heat
When inserting, when may also appear in changer hot drawing, the scheme of prior art is only capable of when solution changer heat is inserted
The problem of existing arcing, but the problem that can not solve arcing occurs during changer hot drawing.
Summary of the invention
The embodiment of the present invention provides the plug-and-play circuit of a kind of changer, occurs during in order to solve changer hot drawing
The problem of arcing.
The embodiment of the present invention provides the plug-and-play circuit of a kind of changer, including output switch and controller, its
In:
One outfan of changer connects the setting pin of transducer side adapter by described output switch；Institute
State transducer side adapter and be additionally included in position detection pin, at described transducer side adapter and system side adapter
During connection, the detection pin in place of described transducer side adapter connects the appointment pin of described system side adapter；
Wherein, the detection pin in place of described transducer side adapter is shorter than other pin of described transducer side adapter；
Described controller, connects for the detection pin in place and described system side determining described transducer side adapter
Whether the appointment pin connecing device connects；If be in closure state at described output switch, described changer is in work
When making state, determine detection pin in place and the appointment of described system side adapter of described transducer side adapter
Pin is not connected with, and controls described output switch and disconnects.
The plug-and-play circuit that the embodiment of the present invention provides, arranges in transducer side adapter and detects pin in place,
For the appointment pin of connection system side-connector, and this detects pin in place and is shorter than in transducer side adapter it
Its pin, during i.e. the connection between transducer side adapter and system side adapter disconnects, transducer side is even
The connection between pin of specifying of the detection pin in place and system side adapter that connect device disconnects at first；Therefore, in output
Switch be in closure state, changer in running order time, if the in place of transducer side adapter being detected
The appointment pin of detection pin and system side adapter is not connected with, then explanation there occurs changer hot drawing, now, control
Output switch processed disconnects so that no longer have electric current to flow through between outfan and the system dc bus of changer,
It is thus possible to avoid the occurrence of arcing, improve the reliability of system.
