Description

Spacecraft power supply buses voltage overshoot detection device
Technical field
The invention belongs to spacecraft-testings and experimental technique field, are related to a kind of spacecraft power supply buses voltage overshoot detection Device, for accessing spacecraft, monitor automatically and judge the spacecraft power supply buses voltage overshoot.
Background technology
At present, most use of domestic spacecraft power supply subsystem divides three domain of configuration to adjust busbar, system topological principle entirely As shown in Figure 1.Shunting signal or boost signal are generated according to busbar voltage, by extra windsurfing power dividing or cell voltage liter Pressure, control bus voltage range usually use VIt is female±VΔIt represents.For example, the satellite generally use busbar voltage in China is 28 ± 1V Or the complete of 100 ± 3V adjusts busbar.
When windsurfing generates electricity it is sufficient when, power management functions generate shunting signal by extra windsurfing power dividing, by busbar Voltage control existsWhen windsurfing generating capacity declines, busbar voltage declines therewith, busbar voltage When, it neither generates shunting signal nor generates boost signal.When busbar voltage drops to It is less than When, power management functions generate boost signal according to busbar voltage, are sent into pulsewidth modulation integrated chip, into Entering PWM controller, PWM controller generates control signal, when pwm control signal is more than 1.0V, the production of pulsewidth modulation integrated chip Raw frequency is fixed, the switching tube for recommending booster circuit that pulsewidth is adjusted according to the adjustable drive signal of signal magnitude, control electric discharge Break-make so that transformer symmetrical operation, to busbar, control bus voltage exists for output after cell voltage is boosted
Due to being linear relationship between busbar voltage and error signal.When busbar voltage drop is less thanWhen, Boost signal more than 1.0V is generated according to busbar voltage, since pulsewidth modulation integrated chip periphery capacitance powers on the charging at initial stage Effect, adjusting the resistance-capacitance circuit of closed loop stability, there are delayed phase characteristics so that boosting is lagged behind in pwm control signal phase There is response delay, busbar voltage caused to continue to drop, boost signal continues to increase, and pwm control signal continues to increase in control signal Greatly, busbar voltage starts lifting;When busbar voltage rises toWhen, although boost signal is less than 1.0V, due to The discharge effect of peripheral capacitance, pwm control signal variation lag behind boost signal, and busbar voltage is still according to the boosting of previous moment Signal is adjusted, and when the voltage up control signal of previous moment is bigger than normal, (previous moment busbar voltage is relatively low, such as less than When voltage up control signal be more than 3.3V, PWM controller will work with maximum duty cycle, and booster will be most to rise higher Pressure energy power is boosted), busbar will generate overshoot.Particularly to powerful pulse-type load, enter shadow region from Yang Zhao areas During, windsurfing output power moment deficiency, busbar voltage rapid decrease, due to prolonging for pwm control signal response can be generated Late so that pwm control signal is excessive, and busbar voltage is caused to generate the overshoot of bigger.
The correctness of test verification busbar voltage control is needed in spacecraft development process, checks the spacecraft disengaging shadow phase Between matching from each offline mode (workload is different), especially during highpowerpulse type loaded work piece, check busbar Voltage controls whether over control occur.
In previous spacecraft model test process, when carrying out busbar voltage control function test job, generally use is such as Lower test method:Spacecraft power supply buses are led to outside spacecraft using transit cable and interconnecting device, by tester's profit Busbar voltage overshoot condition is captured from interconnecting device with oscillograph, data and busbar voltage waveform is recorded, while utilizes busbar electricity Press telemetry parameter auxiliary monitoring busbar voltage overshoot condition (as shown in Figure 2).

2) spacecraft is generally using wireless test, and activity may to wireless signal transmission around spacecraft by tester It impacts, while spacecraft ambient electromagnetic radiation is stronger, tester needs to take radiation protection safeguard measure, Security of test It is poor;
3) since telemetry parameter is discrete magnitude, collection period 500ms, busbar voltage overshoot is generally ms phenomenons, tests Interpretation personnel check the possibility of busbar voltage overshoot substantially less than centesimal probability using telemetry parameter, therefore busbar Voltage telemeering parameter auxiliary monitoring busbar voltage overshoot condition can only be a kind of supplementary means, it is difficult to capture abnormal phenomenon;
4) using interconnecting device and the access module of transit cable, test equipment access system test session is more, beam worker Make and remove receipts heavy workload so that test implementation is relatively complicated.
Therefore, with the development of spacecraft function and application, the load of highpowerpulse type is mating more and more, in spacecraft It is more and more important for the test job of power supply buses voltage control function during ground test is verified, in order to improve spacecraft Power supply buses voltage control function test verification work, further improve test convenience and operability, it is necessary to design one Kind spacecraft power supply buses voltage overshoot detection device, conveniently accessible Space Vehicle System are automatic to monitor and judge that busbar voltage surpasses Phenomenon is adjusted, and test command system is accessed by data-interface, test case is reported to tester, improves the effect of test implementation Rate and convenience.
