Embodiment
Below according to Fig. 1 and Fig. 2, presently preferred embodiments of the present invention is illustrated.
As shown in Figure 1, there is n roads shunt circuit inside satellite power supply controller, work(is connected respectively per shunt circuit all the way
Rate inputs, which can be sun battle array input either storage battery input, and the busbar output of all shunt circuits collects
Exported for the busbar of satellite power supply controller.
The busbar MEA parameters of satellite power supply controller are obtained using voltage sample modulate circuit, busbar MEA is that busbar is defeated
Outlet error is amplified, such as：Busbar voltage design load is 30v, and busbar voltage actual value is 31v, error put it is ten times greater, then it is female
Line MEA is 10v.
All there are two reference voltages per shunt circuit all the way, one is lower voltage limit, and one is upper voltage limit, if female
Line MEA is more than the lower voltage limit of shunt circuit, then the shunt circuit turns on, branch busbar output power.
Illustrated by taking the 1st tunnel shunt circuit as an example, reference voltage 11 is the lower voltage limit of the 1st tunnel shunt circuit, benchmark
Voltage 12 is the upper voltage limit of the 1st tunnel shunt circuit, if busbar MEA is less than reference voltage 11, triode T1 is turned off, the 1st
Road shunt circuit does not work, and the 1st tunnel branch busbar does not have power output；If busbar MEA is more than reference voltage 11 and is less than base
Quasi- voltage 12, then triode T1 is partially ON, emitter output switch control signal G1, metal-oxide-semiconductor the M1 conducting of triode T1, the
1 tunnel branch busbar output power；If busbar MEA is more than reference voltage 12, triode T1 is fully on, the hair of triode T1
Emitter-base bandgap grading output switch control signal G1, metal-oxide-semiconductor M1 conducting, the 1st tunnel branch busbar output power.
Compare the size of busbar MEA and reference voltage 11 and reference voltage 12 using difference amplifier X1, and generate drive
Dynamic base stage of the signal to triode T1.
The circuit shunt principle of satellite power supply controller is by setting reference voltage branch, the base of the 1st tunnel shunt circuit
Quasi- voltage 11 is 0V, and reference voltage 12 is 1V, and when busbar MEA is more than 0V and is no more than 1V, the 1st tunnel shunt circuit is in modulation
Working status；Similarly the reference voltage 21 of the 2nd tunnel shunt circuit is 1V, and reference voltage 22 is 2V, when busbar MEA is more than 1V not
During more than 2V, the 1st tunnel shunt circuit works entirely, and the 2nd tunnel shunt circuit is in modulation working status；Similarly the 3rd tunnel shunt circuit
Reference voltage 31 be 2V, reference voltage 32 is 3V, when busbar MEA is more than 2V and when being no more than 3V, the 1st full work of tunnel shunt circuit
Make, the 2nd tunnel shunt circuit works entirely, and the 3rd tunnel shunt circuit is in modulation working status.
Full working condition refers to：For circuit all the way, just turned on completely to tap, be full work when water is maximum；Entirely
Off state refers to：Screw on completely, a drop is not flowed for shut-off；Modulation working status refers to：Half-open position, flowing water but is less than standard-sized sheet
For modulation condition.Only have in the multiplex circuit branch of satellite power supply controller and only allow to be operated in modulation work shape all the way
State, the i.e. shunt circuit not exclusively shut-off also not exclusively conducting, or and remaining shunt circuit completely work, or completely close
It is disconnected.
, can be by measuring satellite power supply controller busbar MEA values come identification satellite power-supply controller of electric based on this principle
Failure and working status.
The present invention provides a kind of satellite power supply controller working status recognition methods, comprises the steps of：

If the upper voltage limit of the busbar MEA >=shunt circuit, which is in full working condition；
If the lower voltage limit of the shunt circuit<Busbar MEA<The upper voltage limit of the shunt circuit, then the shunt circuit, which is in, adjusts
Working status processed；
Step S3, the working status of satellite power supply controller is judged according to the working status per shunt circuit all the way；
And if only all the way shunt circuit be in modulation working status, then satellite power supply controller is normal operating conditions；
If modulation working status is in without shunt circuit, or the quantity of the shunt circuit in modulation working status is more than
1 tunnel, then satellite power supply controller is malfunction.
It is preferred that it is female to detect acquisition from the output busbar of satellite power supply controller using voltage sample modulate circuit
