12 volt NiCd battery charger circuit diagram This simple schematic shows how to design a 12 V Nicad (nickel cadmium) battery charger circuit by using 555 timer and 78L05 voltage regulator circuit.
The circuit for LED with 220v power supply used a capacitor and a resistor to turn on a LED. It also used a 104 pf of 400/600 volt having a 1 mega ohms connected to pf's both leg which means it's parallel to pf. This circuit c…
Click to enlarge This is also another useful project for anyone working in electronics. Both Current and Voltage Regulation is Extremely Important to Help Prevent Damage to Circuit, Especially Experimental Circuits. This circuit used a …
This is a very useful project for anyone working in electronics. It is a versatile power supply that will solve most of the supply problems arising in the everyday work of any electronics work shop.
This is the schematic diagram of variable power supply. The output voltage of this power supply circuit can be adjust from 0V to 28V DC, while the current output is static the rang is about 6A up to 8A.
The laptop adaptor described here plugs into a car cigarette lighter socket and produces a 19V nominal output voltage adjustable by + - 0.5V. The input voltage range is from 9.2V to 15V and the output voltage shows good regulation even with larg…
Car Battery Charger circuits Schematic Diagram This circuit shows car battery charger that will easily charge most any lead acid battery. The charger delivers full current until the current drawn by the battery falls to 150 mA. At this time, a lowe…
Plus and Minus DC Power Supply Schematic Circuits This is a classic example of a regulated DC power supply that produces both a positive 15v and a negative 15v from a 20vac wall adapter.
Voltage inverter circuit Diagram This voltage inverter circuit powering a dual supply op amp from a single battery problem. The circuit simply takes a positive voltage and inverts it. It uses only one 555 timer and a few other passive components, s…
This voltage inverter schematic can produce a dual (positive and negative) voltage from a single supply input. It is therefore extremely useful for powering opamp and other circuits that require a dual voltage from a single battery. The circuit will …
Lead Acid Battery Charger Schematic Diagram Except for use as a normal Batter Charger, this circuit is perfect to 'constant-charge' a 12-Volt Lead-Acid Battery, like the one in your flight box, and keep it in optimum charged condition. This…
