Description of drawings
Fig. 1 is the utility model circuit theory diagrams.
Embodiment
Below in conjunction with drawings and Examples the utility model dependency structure is elaborated.
As shown in Figure 1, the quick precharging circuit of the utility model comprises optical module and electric module two parts, and optical module comprises resistance R 1, control switch CN1 that is connected in optocoupler module PC1 negative electrode and the LED 1 that is connected in optocoupler module PC1 anode.Described electric module comprises battery that is connected in optocoupler module PC1 collector electrode and the field effect transistor Q1 that is connected in optocoupler module PC1 emitter.Also be connected in parallel to voltage stabilizing didoe DZ1 and capacitor C 1 between battery and the field effect transistor Q1, resistance R 2 one is terminated at the emitter of optocoupler module PC1, and the other end is connected to field effect transistor Q1.When optical module end input electrical signal, light-emitting diode emits beam, and is radiated on the light-receiving device of optocoupler module PC1, and light-receiving device is accepted optocoupler module PC1 conducting behind the light, produce photoelectric current and be output as battery realization charging from output, thus the conversion that has realized " electrical-optical-".
The circuit that described charging circuit both can have been made discrete device separately also can be made independent integrated circuit or be integrated in the integrated circuit as functional module.
