6 FAQs about [How to generate negative power from a battery]
How do I use a battery to create a negative supply?
To use a battery to create a negative supply: Obtain a 9V transistor battery or a 4 or more cell AA alkaline battery pack or other source of 5V or more. (Or a mains "plugpack" power supply of 5V or more.) the -ve terminal will be at -V. eg a 9V battery will give -9V etc. +1 for "use a better op amp".
How can a negative voltage generator circuit be made more efficient?
The circuit can be made more efficient as well as increasing the output voltage by using Schottky diodes instead of generic silicon. This is because Schottky diodes have a smaller forward voltage drop (down to 0.1V), which results in a larger negative voltage. Now that you have a negative voltage generator circuit what can you do?
What is the output voltage of a negative voltage generator?
Here is the output from the negative voltage generator. Note how the voltage is approximately -7.2V because of the double diode drop (1.4V), and the supply was not a perfect 9V but closer to 8.5V. Here is the construction using the 74HC14 oscillator:
How do you get a negative voltage on a power supply?
Basically, you get a negative voltage by calling the positive terminal of the power supply "Zero volts". If you desire a serious amperage, then two power supplies/batteries connected in series is a good choice. The middle point is Gnd. U may use one transformer with two equal windings or one winding transformer with middle point to save a space.
How do you connect a negative voltage without a ground?
To connect negative voltage simply without considering ground at all (which is probably how you'll wire up the circuit most of the time if you're just wiring basic circuits), all you have to do is connect the positive terminal to the ground of the circuit and the negative terminal to part of the circuit you want to connect negative voltage to.
Can a negative voltage generator run off a single rail supply?
Everyone needs a negative voltage rail eventually, but most only have a single rail supply. This project will show you how to build a negative voltage generator that runs off a single rail supply! Everyone needs a negative voltage rail eventually, but most only have a single rail supply.
