Description of drawings
The structural representation of a kind of power supply switched system that Fig. 1 provides for the utility model.
Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in accompanying drawing 1; A kind of power supply switched system; Power supply comprises first power supply 1 and second source 2; The power supply switched system comprises first detecting unit 5 that is used to the first power work state that detects, be used to detect second detecting unit 6 of second source operating state, the controller 4 that is used to cut off the switch 3 of first power supply that breaks down and is used to control first power supply or second source work; First detecting unit 5, switch 3 and second detecting unit 6 include input and output, and the input of first detecting unit 5 links to each other with first power supply 1, and the input of second detecting unit 6 links to each other with second source 2; The output of first detecting unit 5 and second detecting unit 6 all links to each other with controller 4; Controller 4 links to each other with switch 3, and the input of switch 3 links to each other with first power supply 1, and link to each other with the output of switch 3 output of switch 3 of second source 2 is the output of system.
Preferably; First power supply 1 is an AC network, and second source 2 is an accumulation power supply, and accumulation power supply comprises battery pack and converter; The direct current of battery pack output converts alternating current to through converter; Switch 3 is the fast controllable silicon fling-cut switch of switching speed, and first detecting unit 5 and second detecting unit 6 are voltage sensor, and controller 4 is TMS320F2812.
During operate as normal, switch 3 closures, first power supply 1 is load 10 power supplies; The output of second source 2 no-voltages, the voltage sensor of first detecting unit 5 detect the output voltage amplitude and the frequency of first power supply 1 in real time, and detected information is sent to controller 4; When the amplitude of input voltage and frequency occur when unusual; Controller 4 cut-off switch 3 are controlled second source 2 beginning output voltages simultaneously, and second detecting unit 6 is the operating state of monitoring second source 2 in real time; The output voltage of controller 4 control second sources 2 is followed first power supply, 1 unusual preceding voltage-phase; Because switch 3 adopts the controllable silicon fling-cut switch, switch speed is the microsecond level, can realize the uninterrupted power supply of load.
First detecting unit 5 is monitored the voltage magnitude and the phase place of first power supply 1 in real time and is sent to controller 4; When the amplitude of input voltage with bit recovery normal level mutually and after keeping a period of time; Controller 4 assert that first power supply 1 has recovered normally, controller 4 control switchs 3 closures when first power supply 1 is identical with phase place with second source 2 output voltage amplitudes, and the power output of control second source 2 reduces; Finally be in the output of holding state inactivity; System normally moves, because the closing speed of switch 3 is very fast, so can realize not occurring in the handoff procedure obvious cutout.
