Control panel feeder ear, and conducting preset time is carried out, so that at the voltage difference at the capacitor both ends on the control panel of direct current generator
In in preset range；
Then, single-chip microcontroller output second control signal control is high level, then the second triode Q14 is connected, thus
So that the second field-effect tube U22 and the 4th field-effect tube U24 conducting, makes its battery VCC by being supplied to direct current after field-effect tube
The control panel end of machine, to bypass preliminary filling resistance.
Aforesaid way can reduce direct current generator starting immediate current very much, and normally after starting, battery power supply
Also normal.During the direct current generator to different capacity is powered, it can be very good to play the role of stable power-supplying power supply, with
And also there is protective effect to battery battery core.
To sum up, provided by the embodiment of the utility model a kind of for reducing the control circuit and dress of direct current generator power spikes
It sets, preset time is first connected by controlling the first power control module, so that the power supply signal of battery output flows through the first power supply
After control module, the capacitor in DC motor control circuit is pre-charged by preliminary filling module, is avoided to direct current generator
The immediate current being powered is excessive；Then it controls the first power control module and the second power control module is connected together, then
Second power control module bypasses preliminary filling module, so that circuit function is normal after direct current generator normally starts.By
This realizes the electric current that can reduce power supply moment, and does not influence its power supply capacity；Protect inside battery device well simultaneously,
The stability for improving system, solve existing power supply technology there is power supply immediate current it is excessive, cause to battery
The problem of internal device causes adverse effect.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
