No light! because of a low voltage battery. How do you increase the voltage up? You can do many ways. And, I recommend a simple step-up converter circuit using TDA2822.
Oh…Low voltage source. A load does not run. Use these circuits. They will convert that voltage to a new voltage as you need. With 2 groups: Inverters—the output is AC voltage like AC main. DC converters—the output is DC voltage.
You would like to use electrical appliances outside the home that no electricity.
We recommended you use a battery and inverter circuit, it can convert a 12V battery to AC voltage, is same as AC line at your house.
Here! We have a many the inverter circuit, 10-watts,60W, 100W, 200W, and 500W power output. It can convert a 12VDC to 230VAC 50Hz/ 220VAC 50Hz/ 110VAC 60Hz output as your country.
You can learn how it works in a simple circuit. To begin with, you see transistors circuits are so easy. Next, power MOSFET circuits are hight watts and easiest. Final, we use ICs circuit are so easy and small size.
We use the parts in all circuits are available in most of the local markets.
See many inverter circuits below.
I like the 12V LED. But I have only 3V of batteries. So, No light. When using this circuit, I can get light of the LED at 100 mA. And, an adjustable output voltage.
This is a simple DC to AC Converter circuit,to converts 12VDC to 220VAC 50Hz/110V 60Hz as adjust frequency output using CD4047,MOSFET,power transistor and more
This is small high volts shock circuit, pressure from the low current. It is perfect for fun play. In circuit has a few component just two small NPN transistors, 2 resistors and a transformer. So easy to builds and cheap! Do not wait..lets build it.
Small appliances have microcomputer that requires 5V power supply. Why it can use only 1.5V battery? The 1.5V to 5V boost converter circuit inside them.
it is the well-regulated power supply. We use it as the simple step down 12v to 9v converter circuit. It can give the output current up to 4A.
