Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
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 an 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 electrical input and storage battery electricity output, described accumulator output end is electrically connected with extraneous load, described storage battery electrical 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 adjustment device 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 to provide the energy in a servo negative feedback closed loop system that system forms; Storage battery is load; Detector is used for detection signal; Control circuit is used for the analysis and judgement signal; Servomotor, switch combination circuit are used for carrying out 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, under same output winding number of turn situation, output voltage also reduces, but controller sends to instruct and makes change over switch with two generators output winding series connection (as shown in Figure 5) simultaneously, 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 generator output voltage on the whole and stabilize to predeterminated voltage, though 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 transferred greatly, generator speed is improved, output voltage improves, controller sends to instruct and makes change over switch with two generators output winding parallel connection (as shown in Figure 4) simultaneously, 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 balance, keep the stable of generator output voltage on the whole with generator speed.Generator raising this moment electric weight is bigger, to satisfy the needs of unsaturated cell large current charge.
