6 FAQs about [Use batteries to increase the voltage of the voltage regulator]
Why do I need to increase the voltage of a battery?
Increasing voltage is less effecient, which is why when needing to increase the voltage your generally better wiring batteries in series (the voltage of each battery adds together) The catch is, if you use a lower voltage and you have a device (motor or kettle) that uses a high amount of watts, you need more current to supply that.
How do voltage regulators work?
Voltage regulators are placed in series with the idea of increasing the output voltages. This is similar to connecting two batteries in series: the two battery voltages will sum according to Kirchoff’s voltage law, but the current in each battery would be the same according to Kirchoff’s current law.
How can a power regulator reach a higher voltage?
To reach a higher voltage than might be available from a single power regulator, it is possible to connect two power regulators together in series. In other words, the output (GND) from one regulator is connected to the input (PWR) of the next regulator.
Why does a discharged battery prevent the regulator from achieving 14.4 volts?
A discharged battery prevents the regulators from achieving 14.4 volts because of its low internal resistance. Voltage and resistance (ohms) are in control, amps do what they are damn well told by Ohm’s Law. The battery controls the resistance. The regulator (s) control the volts only after the acceptance part of the cycle starts.
Should a switching regulator increase or decrease voltage?
Decreasing voltage is quite effecient when using a switching regulator. Increasing voltage is less effecient, which is why when needing to increase the voltage your generally better wiring batteries in series (the voltage of each battery adds together)
How does a switching regulator work?
A switching regulator converts the DC input voltage to a switched voltage applied to a power MOSFET or BJT switch. The filtered power switch output voltage is fed back to a circuit that controls the power switch on and off times so that the output voltage remains constant regardless of input voltage or load current changes.
