State often:
Connect the 220V civil power, green LED LED2 is luminous, and showing has civil power.The cathode voltage that is higher than controllable silicon KG simultaneously because of the partial pressure value on resistance R 10, the R11+R12 (being the control pole tension of controllable silicon KG), controllable silicon KG conducting begins the charging to storage battery E, and red light emitting diodes LED1 is luminous, shows and charges.Behind storage battery E full charge, the cathode voltage of controllable silicon KG is near the control voltage of controllable silicon KG, and controllable silicon KG turn-offs, and stops charging.
When the charge circuit short circuit, the grounded emitter of triode Q2, triode Q2 is saturation conduction also, and emitter equates that with collector voltage is approaching controllable silicon KG turn-offs, and blocks the electric current in the charge circuit, thus the protection charge circuit does not burn because of electric current is excessive.
