Condition customization, the condition customization of giving and accepting refer to that load-side proposes that the customization of voltage and current is wanted to source side according to self-demand
Ask, this process includes two steps: 1) after source side is connected and powered on load-side, connection electric current is zero, i.e. zero current threshold
Value is hereinafter, line voltage is increased to after threshold voltage after starting the first timing section timing and continuing to rise to calibration voltage,
Load-side is by the demand of give and accept voltage and maximum current i.e. electric current customization of post-back to source side in the period of one timing section, it is assumed that
At this time without path drop, i.e., voltage readings and maximum current demand are passed back to by power supply by pulse train using when no current
Side；2) after the time interval of the first timing section enter the second timing section, at this time will connection current boost to one it is lesser
Electric current is calibrated, the calibration current value and voltage of reading are required to be voltage customization of post-back to source side, i.e., by low current by load-side
When current indication and voltage require to pass back to source side, now assume that no electric leakage, realized with this to source side electric current and electricity
The customization of pressure.
9. a kind of power supply according to claim 1 customizes connection method, which is characterized in that the customization connection is using safety
It attempts, the safety, which is attempted to refer to, safely starts different output voltage limitations, when output voltage reaches some voltage range
Load-side needs to reduce electric current to range as defined in IV i.e. changed power window is met when the upper limit, at this moment source side reduce current limliting,
Output attempts to promote a limited voltage increment；If electric current is still maintained in IV window after voltage increase, continue to open
It is attempted with the limitation of the voltage and current of next stage, until 1) voltage can not promote desired point voltage increment because of electric current raising；
Or 2) electric current is further decreased into hold mode, continues this process until finding highest safe voltage.
10. a kind of power supply customizes attachment device, which is characterized in that including source side and load-side, the load-side has load
Side-connector, pulse generation circuit and voltage/current detection circuit, the voltage/current detection circuit pass through the pulse
Generative circuit connects the load side-connector, and the load side-connector connects source connection by the cable link
Device；The source side has voltage/current output control circuit and pulse receives timing circuit, and the pulse receives timing
Circuit and the voltage/current output control circuit are all connected with the source connector.
