Embodiment
By describing technology contents of the present invention, structural feature in detail, realized purpose and effect, below in conjunction with execution mode and cooperate that accompanying drawing is detailed to give explanation.
See also Fig. 2, present embodiment provides a kind of electric power system, described electric power system comprises generator, internal combustion engine and storage battery, described generator is internal rotor permanent-magnetic body generator and by internal combustion engine drive, described generator has output winding and the dynamo-electric output of generating, described output winding is electrically connected with the dynamo-electric output of generating, described storage battery has storage battery input and storage battery output, described accumulator output end is electrically connected with extraneous load, described storage battery input is electrically connected with the dynamo-electric output of generating, be provided with change over switch between the output winding of described generator and the dynamo-electric output of generating, described generator output winding is divided into two groups that umber of turn equates, and change over switch has makes two groups of coils from parallel connection of coils or the two kinds of gears of connecting.System is provided with detector, controller and throttle for IC engine adjuster, described throttle regulator comprises throttle adjustment valve and the stepping motor that drives the throttle adjustment valve, described detector is electrically connected with battery, and described controller is electrically connected with stepping motor and change over switch in detector, the throttle for IC engine adjuster.
It is that (wherein internal combustion engine is used for providing the energy in a servo negative feedback closed loop system that system forms; Storage battery is load; Detector is for detection of signal; Control circuit is used for analyzing the judgement signal; Servomotor, switch combination circuit are used for execution action.)
When accumulator electric-quantity during greater than set point, detector detects signal and sends to controller, controller sends instruction makes the throttle for IC engine adjuster that throttle for IC engine is turned down, generator speed is reduced, in same output winding number of turn situation, output voltage also reduces, but sending instruction with Time Controller makes change over switch with two generators output winding series connection (as shown in Figure 5), thereby the coil turn that is connected with generator output end is increased, generator output voltage is improved, the output voltage that causes owing to generator speed reduces with balance lowers, keep on the whole generator output voltage and stabilize to predeterminated voltage, although this moment, the generator output current reduced, be enough to keep the storage battery needs that charge when more saturated.
When accumulator electric-quantity during less than set point, detector detects signal and sends to controller, controller sends instruction makes the throttle for IC engine adjuster that throttle for IC engine is tuned up, generator speed is improved, output voltage improves, sending instruction with Time Controller makes change over switch with two generators output winding (as shown in Figure 4) in parallel, thereby the coil turn that is connected with generator output end is reduced, and then the output voltage of reduction generator, improve by improving the output voltage that causes with generator speed with balance, keep on the whole the stable of generator output voltage.Generator raising this moment electric weight is larger, to satisfy the needs of unsaturated cell large current charge.
The energy separates with load in the handoff procedure of coil, and when throttle is adjusted to when suitable, the energy and load are connected.So just do not need to consider the problem that seamlessly transits of voltage.When if extraneous load request does not cut off the power supply, can in circuit, add storage capacitor.
Throttle adjustment valve in the present embodiment in the throttle regulator is driven by stepping motor, makes the throttle size control more accurate.
Changing the coil turn that links to each other with generator output end in the present embodiment reaches by parallel connection or series coil mode, take full advantage of so whole coils, electric current is little when series connection, thinner circle line can meet the demands, when the large electric current of needs, because two parts coils from parallel connection of coils, two parts coil is shared the part electric weight like this, can use equally thinner circle line, save material, lower cost.
