Accu charger use a diac and triac
This circuit can be used to charge Accu and cells battery , the circuit can has a very stable output that would make the battery last longer and maximize the added battery capacity. When charge was also quite fast , so it can optimize the time.
A diac is used in the gate circuit to provide a threshold level for firing the triac . C3 and R4 provide a transient suppression network. R1 , R2 , R3 , C1 , and C2 provide a hase - shift network for the signal being applied to the gate. R1 is selected to limit the maximum charging current at full rotation of R2.

Power Supply with regulator output use IC uA723
This circuit operating with IC uA723 and add amplified with transistor TIP31 or similiar transistor with TIP31 . Input voltage for circuit about 10 - 40 volt DC , formerly of AC voltage 220 volts or 110 volts , then lowered by the transformer voltage to 30 volts. And the supply output voltage from 1 volt to 35 volt DC you can adjust it on potentiometer R2.
See this circuit power supply below :
Output voltage transformer used 10 to 40 Volts . On resistor Rsc is the current limit set resistor. Its value is calculated as :
Rsc = 0.65 Volt For Example : If you need current output 2.0 A
Rsc = 0.65 / 2.0 = 0.32 Ohm So , you must use 0.32 Ohm to current output 2.0 A

Solar Charger use IC LM317
At this point is a Solar Charger Circuit to is used to charge information Acid otherwise Ni-album batteries using the solar energy power. The circuit harvests solar energy to charge a 6 volt 4.5 Ah rechargeable battery in favor of various applications. The stallion has Voltage and Current supervision and terminated voltage restrict sour facilities.
Circuit uses a 12 volt solar panel and a changeable voltage supervisor IC LM 317. The solar panel consists of solar cells each one rated on 1.2 volts. 12 volt DC is presented from the panel to charge the battery. Charging current passes through D1 to the voltage watchdog IC LM 317. By adjusting its Adjust pin, output voltage and current can subsist regulated.

| Solar Charger use IC LM317 Schematic |
VR is placed amid the adjust pin and ground to provide an output voltage of 9 volts to the battery. Resistor R3 confine the charging current and diode D2 prevents discharge of current from the battery. Transistor T1 and Zener diode ZD conduct yourself having the status of a stop rotten switch at what time the battery is ample. Normally T1 is rancid and battery gets charging current.
After the terminal voltage of the battery rises over 6.8 volts, Zener conducts and provides station current to T1. It followed by turns on education the output of LM 317 to prevent charging. If you want to specific voltage / current output , you can replacing ZD on the circuit above.
