6 Frequently Asked Questions about “How to convert lithium battery into dual-wire power supply”

How do you use a dual power supply?

For a quick and simple dual power supply, use two resistors in series connected in parallel with two capacitors. Connect the two ends to the battery or power source and BAM! You have a dual power supply. Typical values for bipolar converters like this are 100k-1M for the resistors and 47uf to 4700uf depending on the current draw of your circuit.

What is a dual power supply from a single battery?

The power supply can be single or dual. A single supply creates only one voltage, but a dual supply produces two voltages, one positive and one negative. This article focuses on the dual power supply in particular. So we have decided that in this tutorial, we are going to make a “Dual Power supply from a single battery”.

How can I use a line-powered switching power supply instead of a battery?

simulate this circuit – Schematic created using CircuitLab If you always want to use the line-powered switching power supply in preference to the solar-charged battery, then arrange that power supply to put out a little higher voltage than the battery. It doesn't need to be much, even just a few 100 mV would do it.

How many volts does a dual output dc/dc converter provide?

In my previous project, the system was wire-powered by USB and made use of an isolated dual output DC/DC converter which provides a ±3.3V, so with two LDO positive and negative regulator I obtained the ±2.5V. Now I want to transfer the project in a portable contest and I need to make some changes to reduce the system size.

How do you charge a battery with a diode?

Arrange the power supply voltage to be the battery float charge voltage after the diode. You can think of the battery as always providing the power, and the power supply charging the battery when on. You could also make that preferential use of one over the other work using diodes of different forward voltages.

How do you charge a battery with a Schottky diode?

Another possibility is to connect the battery directly, and the power supply thru a Schottky diode. Arrange the power supply voltage to be the battery float charge voltage after the diode. You can think of the battery as always providing the power, and the power supply charging the battery when on.
