Accompanying drawing explanation
Fig. 1 is one embodiment of the present invention schematic circuit diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
Trackless trolley car power system as shown in Figure 1, comprising: a drive motor, and drive motor and main reduction gear are in transmission connection; An integrated manipulator, integrated manipulator AC drives control linkage drive motor, integrated manipulator DC side connects DC bus, on DC bus, be connected with super capacitor system and isolated DC/DC current transformer, isolated DC/DC current transformer input end connects current colector, and mouth connects DC bus; An electrokinetic cell system, electrokinetic cell system connects input end or the mouth of described isolated DC/DC current transformer by a change-over switch, change-over switch is in figure during A point, electrokinetic cell system is connected to DC/DC mouth, when B point, electrokinetic cell system is connected to DC/DC input end.
Further, can on DC bus, go here and there and be provided with for preventing that braking energy is to the diode of electrokinetic cell system feedback, the interface of super capacitor system, electrokinetic cell system and DC bus is respectively in these diode two ends.
With the supporting controller that is provided with of trackless trolley car power system, controller is for the coordination of whole power system is controlled, as integrated manipulator dependent instruction is controlled, sent to isolated DC/DC current transformer; Gather the various electric parameters in power system, as bus voltage, electrokinetic cell voltage, current colector open and-shut mode etc.Controller can arrange separately, also can be served as by entire car controller, as shown in this embodiment.
Integrated manipulator is a kind of controller that includes the integrated form of electric machine controller, and integrated manipulator is simultaneously integrated inverter is drive motor power supply for direct current (DC) being changed into controlled alternating current.
Current colector is electrically connected to gauze, and the electrical energy transfer of gauze is arrived to electric car power system.
Current colector is given DC bus powered by isolated DC/DC, thereby to whole system power supply, isolated DC/DC realizes electrical isolation by car load and gauze, avoids producing step voltage.Diode can prevent that feedback energy is recycled in battery, has improved the work efficiency of power-supply system.
During car load linked network, change-over switch is in A point, and electrokinetic cell system is connected to the mouth of DC/DC.During car load off-grid, switch is in B point, and electrokinetic cell system is connected to the input end of DC/DC, and DC/DC is reused, and has improved service efficiency.
