Simple Inverter Circuit from 12 V up to 120V elevated

Image
This is a simple 120 V : 24 V , center - tapped ( CT ) control transformer and four additional components can do the operation. This circuit outputs a clean about 120 volt - 200 volt at 60 Hz and can supply up to 20 Watt . The circuit is self starting and free running. See this simple inverter circuit below : Transistor Q1 and Q2 use 2N5877 or similarity .If Q1 is faster and higher gain than Q2 , it will turn on first when aplly the input power and will hold Q2. Load current and the transformer magnetizing current the flows in the upper half of primary coil, and auto transformer supplies the base drive (two transistor) unti the transformer saturates.The transformator can use the 3A CT transformer an use the secondary coil for input and primary coil use to output, And input use the 12 volt secondary coil. Use 12 battery to power input , such as 12 V accu. You can use the circuit at the time of death PLN electricity , using 12 volt battery or accu , you can turn n a fluorescent...

Step Down Battery Charger From Solar Panel

Image
This is very simple and low-cost Electronic Circuit Project of step-down battery charger from solar panel. Using the LT3652 step-down battery charger which operates over a wide range input voltage can be build a very simple solar charger. The LT3652 provides a constant-current constant-voltage charge characteristic with maximum charge current externally programmable up to 2A. The desired output voltage can be up to 14.4V, programmed with a resistor divider. Step-Down Battery Charger From Solar Panel Circuit Diagram: When the LT3652 is powered by a solar panel, the input regulation loop is used to maintain the panel at peak output power. The LT3652 can be configured to stop charging when charge current falls below 1/10 of the maximum programmed and an new charging cycle starts if the battery voltage falls 2.5% below the programmed float voltage. When the charging process is over the LT3652 enters in a low-current mode (85μA standby mode). The LT3652 can be also programmed to stop the ch...
