Consult Fig. 1.In embodiment described below, engine electronic control system device self adaptation DC-DC booster power system is mainly made up of redundant circuit 3, both-end pulse modulated circuit 4, single-ended drive circuit 5, filtering output circuit 6 etc.Wherein, three-phase alternating-current supply 1 and battery feed 2 are electrically connected both-end pulse modulated circuit 4 by redundant circuit 3, redundant circuit 3 is connected with single-ended drive circuit 5 with both-end pulse modulated circuit 4, and single-ended drive circuit 5 is electrically connected the direct output supply voltage of filtering output circuit 6.Both-end pulse modulated circuit 4, single-ended drive circuit 5 and filtering output circuit 6 form booster circuit.
When redundant circuit 3 detects that three-phase alternating-current supply 1 and battery feed 2 one of them voltage are when high, just by redundant circuit 3, redundant circuit 3 can detect a high voltage of output.
Both-end pulse modulated circuit 4 relatively detects that voltage that redundant circuit 3 comes is lower than setting voltage value, and both-end pulse modulated circuit 4 is started working, and low-voltage is elevated to set point.
After engine start, because the operating current of engine has reduced several times than starting current, battery tension just goes back up to about 28 volts.Both-end pulse modulated circuit 4 relatively detects that the voltage of redundant circuit 3 through coming is higher than the magnitude of voltage arranging, both-end pulse modulated circuit 4 is not worked, and voltage is powered to engine electronic control system device through redundant circuit 3, single-ended drive circuit 5 and the direct output supply voltage value of filtering output circuit 6.Under this operating state, both-end pulse modulated circuit 4 and single-ended drive circuit 5 are not worked completely, and operating current reduces, caloric value reduces, power consumption is also low, has improved reliability.
When both-end pulse modulated circuit 4 relatively detects that voltage that redundant circuit 3 comes is higher than setting voltage value, both-end pulse modulated circuit 4 is not worked, and voltage is through redundant circuit 3, single-ended drive circuit 5 and the direct output supply voltage of filtering output circuit 6.
When both-end pulse modulated circuit 4 relatively detects the voltage of redundant circuit 3 through coming lower than set point, the pulse that both-end pulse modulated circuit 4 produces a natural frequency drives single-ended drive circuit 5, the pulse that single-ended drive circuit 5 produces and filtering output circuit 6 form booster circuit, voltage is raised to set point and powers to engine electronic control system device.
In the time of ato unit not, battery feed is powered to engine electronic control system device.Engine start immediate current is very large, and moment drops to battery tension very low, engine electronic control system device self adaptation DC-DC booster power startup work, moment low-voltage be elevated to set point; In the time that battery tension goes back up to certain value, can set, engine electronic control system device self adaptation DC-DC booster power is directly exported; Engine start, in the time of slow train, is transformed into alternating current generator power supply automatically, and alternating current generator mains ripple is large, through engine electronic control system device self adaptation DC-DC booster power supply circuit, then exports to engine electronic control system device system power supply.In the time of alternating current generator power down, can automatically be transformed into direct-flow storage battery power supply, when direct-flow storage battery power down, can automatically be transformed into alternating current generator power supply.
When engine start is during near slow train, the supply voltage of three-phase alternating current engine is approximately greater than battery tension, and redundant circuit 3 detects that one of them voltage is higher than another voltage, is just automatically transformed into three-phase alternating-current supply 1 by redundant circuit 3 and powers; When three-phase alternating-current supply 1 power down, can automatically be transformed into battery feed 2 by redundant circuit 3 and power; In the time of battery feed 2 power down, automatically change three-phase alternating-current supply 1 by redundant circuit 3 and power.This engine electronic control system device self adaptation DC-DC booster power provides reliable, stable electric power system to engine electronic control system device.
