Serial voltage stabilizing circuit with few residual Voltage
This circuit uses the collector of serial transistor as output terminal, the minimum voltage difference between lowest roll in voltage and steady output voltage can reach 1.2V. Adopting two regulator tubes can ensure the output voltage with high stability. Using 2.5kΩ potentiometer can set output voltage to the given value. 1nF capacitance can suppress high frequency oscillation. (View)

Larger current steady voltage circuit with current limit
In figure, the choice of resistances R1 and R2 should meet the condition of R2≧5*R1. Such as R1=0.2Ω, R2=1Ω. In practice, according to the current, R1 should be between 0.1~2Ω, because of UBE=UD, then UR1=UR2, so I2 is lower than 5 times of I3, total current I1=I2+I3≈I4, neglecting the base current of transistor, then I3 is equal to the adjustment current of integrated circuit IC. For large current transistor, the resistance R3 can be selected between 10~20Ω. For small current transistor, the resistance can be choiced of 100Ω. (View)

A kind of full automatic charger circuit
working principleDiagram 4-27 is the principle diagram of this charger. The voltage of LM339's pin 5 V5=6V. When the battery voltage E is less than 12V, V4 is less than 6V. LM339's pin 2 outputs high level. It can let 9013 saturation. 3AD30 is on amplified state. The measured value is 300mA when using heavy current to charge. When E≥12V, V5≥6V. LM339's pin 2 output low level. 9013 and 3AD30 is cut off. It adopts 40mA low current to charge to the battery. The curved line of measured charge current is shown in diagram 4-28. (View)
