It is connected with capacitor C, and capacitor C is electrolytic capacitor, polarized electrolytic capacitor is usually in power circuit or intermediate frequency, low-frequency channel
The effects of playing power filter, decoupling, signal coupling and time constant setting, stopping direct current.It fundamentally cannot be used AC power circuit,
Make filter capacitor in DC power supply circuit in use, its anode (anode) should be connected with the positive terminal of supply voltage, cathode
(cathode) is connected with the negative pole end of supply voltage, cannot be reversed, otherwise can damage capacitor.Therefore in only mains-supplied
In the case of, the 5th circuit 105 is in an off state, at this time 104 circulating current of only the 4th circuit, and the electric current of third power supply V3 needs
Reduce electric current first, since the electric current of alternating current is larger, suddenly by electric current input bus 2 when will cause the voltage jump of bus 2, from
And the capacitor C connected in bus 2 is damaged, so first to drop stream, capacitor C is connected the electric current then reduced, so that the 4th
Circuit 104 forms the circuit of a closure, in capacitor C conducting, when needing to open five circuits 105, needs to disconnect the at this time
Four circuits 104, and the 5th circuit 105 is opened, so that the 5th circuit 105 works normally, since alternating current is alternating current, and
Auxiliary source 3 needs direct current, therefore the effect of the 5th circuit 105 is the direct current of alternating current to be become alternating current, and then meet auxiliary source 3
Power demand.
4th circuit 104 is equipped with rectifier bridge N, and third power supply V3 positive terminal and negative pole end are connect with the input terminal of rectifier bridge N,
