The Car Voltage Regulator (How It Works + How To Test It)
If the charging voltage drops below 13.5V, the regulator supplies additional current to the field winding to charge the alternator. If the voltage level rises above 14.5V, the regulator will stop delivering the power supply to the field winding and prevent the alternator from charging. So how does the voltage regulator ensure constant voltage?

6 Signs Of A Bad Or Failing Voltage Regulator
But your battery can only handle up to 14.5 volts at a time (12.6 volts is a full charge). If the alternator kept dumping all that voltage into the battery, it would blow up! Your voltage regulator monitors your battery''s current-voltage and sends voltage that way when it starts to dip too low.

Choosing the right power regulator for Battery powered designs
Battery powered projects (particularly those with periodic events spaced quite a bit apart) usually benefit from using a linear regulator.. Looking at your requirements (LiPo 4.2V to Vo + dropout voltage) a linear regulator will be (on average 3.7V battery, regulated output 3.0V) 81% efficient which is close to the SMPS solution anyway.
Understanding the Alternator Voltage Regulator Diagram: A Step …
The voltage regulator works by controlling the field current in the alternator''s rotor. The rotor is an electromagnet that produces a magnetic field when current flows through it. By adjusting the field current, the voltage regulator can control the strength of the magnetic field, which in turn determines the output voltage of the alternator.

Batteries Regulation
On 10 December 2020, the European Commission published its proposal on the new Batteries Regulation, which replaces the current Batteries Directive (2006/66/EC). This is a long-awaited and crucial piece of legislation, defining the legislative framework for our industry for the next 15 years.
Driving Diode Lasers: A Straightforward Procedure
The regulator circuit compensates for this with an ever-increasing laser current in an attempt to keep the output power constant. Without a current limiter or safety shutdown circuit, the diode could be damaged or even destroyed. Automatic power control employs a monitor diode integrated into the laser package for feedback.

How Automotive Voltage Regulators Work
Rev the engine to 2,000 to 2,500 rpm for 10 to 15 seconds. This should trigger the regulator to kick in and output its full voltage. Check the meter again. It should show 14 to 14.5 volts. If the output is the same as the resting battery voltage, the regulator is not working. If the output is above 14.5 volts, the regulator is not working.
PWM solar charge controllers: A quick and thorough explanation
Lithium battery cell charging voltage and current. When the battery is at a low state of charge and starts charging, its voltage slowly ramps up as the PWM stays on to allow as much current as possible into the battery. But when the battery is almost fully charged, its voltage stabilizes at a certain value (around 13.6V for 12V batteries).
