Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of aptitude chargeable circuit, including rectifier bridge Q, resistance R1, electric capacity C, diode D1, audion VT1, diode CW1, one-way SCR VS1 and one-way SCR VS2, described rectifier bridge Q pin 1 and rectifier bridge Q pin 3 connect 220V alternating current two ends respectively, rectifier bridge Q pin 3 is also respectively connected with audion VT1 colelctor electrode, the A pole of diode CW2 positive pole and one-way SCR VS2 ground connection, rectifier bridge Q pin 2 connects electric capacity C respectively, resistance R1 and diode CW1 negative pole, diode CW1 positive pole connecting triode VT1 base stage, audion VT1 colour former connects resistance R2 and diode D1 positive pole respectively, the resistance R2 other end connects the resistance R1 other end respectively, the electric capacity C other end and rectifier bridge Q pin 4, diode D1 negative pole connects the G pole of resistance R4 and one-way SCR VS2 respectively, the K pole of one-way SCR VS2 connects the resistance R4 other end respectively, the A pole of diode D2 positive pole and one-way SCR VS1, diode D2 negative pole connects resistance R6, the resistance R6 other end connects diode CW2 negative pole respectively, the G pole of resistance R5 and one-way SCR VS1, the K pole of one-way SCR VS1 connects ground connection accumulator E positive pole and the resistance R5 other end respectively, described diode CW1 and diode CW2 is Zener diode.
Operation principle of the present utility model is: refer to Fig. 1, electric capacity C charging is given after the rectified bridge Q of 220V alternating current, when the voltage on C makes CW1 puncture, VT1 turns on, VS2 is triggered conducting until alternating current positive pressure half cycle terminates, constantly repeat above procedure, make the negative half-wave in each cycle that 220V alternating current exports all some because VS2 conducting clipped wave, if the fluctuation of 220V alternating current causes that voltage raises, the charging of C is accelerated, the angle of flow of VS2 also increases therewith, limit the rising of voltage, if the fluctuation of 220V alternating current causes that voltage declines, when the upper voltage of C is not enough to make CW1 puncture, VS2 ends, when the instantaneous value of rectifier bridge Q output exceedes accumulator E voltage, D2, R5, R6 flows through forward current, when trigger voltage more than VS1 of the pressure drop of R5, VS1 turns on, accumulator E is electrically charged, if accumulator E charging voltage exceedes circuit configuration value, clamping action due to CW2, make R5 electric current reverse, VS1 ends, prevent the overcharge of accumulator E.
