BATTERY OPERATED SYSTEM DESIGN CONSIDERATIONS The topology selection is the first step of a portable power circuit design. It is mainly based on the input and output voltage rating, as shown in Fig. 18. If the input voltage is higher than the output at any time, a Buck converter or LDO is normally the only solution.
Using Autodesk Circuits and a lead-acid battery, you can create a circuit that will act as a variable power supply, outputting a range of voltages from 5V to 20V. After creating the power supply you could drive motors using variable voltage, power microcontrollers, logic circuits, LED strings, analog circuits, and much more.
Some design considerations associated with portable power design have been discussed, such as light load efficiency, voltage regulation accuracy, the battery impedance impact on the end of discharge voltage, battery discharge efficiency and system stability. A portable device needs a battery as its power source when an AC adapter is not available.
A basic power supply circuit will fundamentally require three main components for providing the intended results. A transformer, a diode and a capacitor.The transformer is the device which has two sets of windings, one primary and the other one is the secondary.
The power supply system should operate at high efficiency at the nominal load current. Some systems have to operate in a standby mode where the load current is reduced to a few milliamperes or even down to the microampere range when no backup batteries for RAM and real time clock are used.
After creating the power supply you could drive motors using variable voltage, power microcontrollers, logic circuits, LED strings, analog circuits, and much more. This is a good way to learn how basic electronic components can be put together, like a puzzle, to accomplish a task.
