How does a simple voltage regulator work?
A simple voltage/current regulator can be made from a resistor in series with a diode (or series of diodes). Due to the logarithmic shape of diode V-I curves, the voltage across the diode changes only slightly due to changes in current drawn or changes in the input.

Electronic circuits are dependent on voltage regulators since they require a stable voltage supply to avoid damage.
How does a shunt regulator work?
A shunt regulator is used for low-powered circuits. It works by directing the current away from the load and sending it into the ground. It provides a path from the input voltage to a variable resistor which is connected to the ground. It has a very low efficiency but since the wasted current has a very low value, it is neglected.
Why does my car battery voltage drop when starting?
During cold weather conditions while starting the car, the battery voltage may drops significantly low. As soon as the engine has ignited the battery's internal resistance also become quite low, forcing it to pull too much current from the alternator and thus leading to a possible deterioration of the alternator.
How does IC1 work?
IC1 works like a a voltage comparator which tracks the dynamo output voltage. As the dynamo output voltage increases the voltage on the op amp inverting input is at first greater than at the non-inverting input, hence the IC output is held low and T3 remains switched off.
What is the 3rd relay?
There's also a 3rd relay containing its coil winding in series with the dynamo output, through which the entire dynamo output current passes. Once the safe output current of the dynamo gets dangerously high, may be due to over discharged battery, this winding activates the relay.
Why is a diode D3 used?
Diode D3 is incorporated to avoid current becoming drawn from the field coil due to the reduced armature resistance of the alternator. As the speed of the engine increases the output from the dynamo proportionately rises, and starts delivering its own field current by means of D3 and T1.
Do cars have voltage regulators?
While most contemporary cars are furnished with solid-state voltage regulators to regulate the voltage and current output from the alternator, you may still find countless earlier cars installed with electromechanical type of voltage regulators that happen to be potentially unreliable.
How does voltage regulation work?
In electromechanical regulators, voltage regulation is easily accomplished by coiling the sensing wire to make an electromagnet. The magnetic field produced by the current attracts a moving ferrous core held back under spring tension or gravitational pull. As voltage increases, so does the current, strengthening the magnetic field produced by the coil and pulling the core towards the field. The magnet is physically connected to a mechanical power switch, which opens as the magnet moves into the field. As voltage decreases, so does the current, releasing spring tension or the weight of the core and causing it to retract. This closes the switch and allows the power to flow once more.
What is voltage regulator?
A voltage regulator is a system designed to automatically maintain a constant voltage. A voltage regulator may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages .

Generators, as used in power stations, ship electrical power production, or standby power systems, will have automatic voltage regulators (AVR) to stabilize their voltages as the load on the generators changes.
What is a shunt regulator?
If the stabilizer must provide more power, the shunt regulator output is only used to provide the standard voltage reference for the electronic device, known as the voltage stabilizer. The voltage stabilizer is the electronic device, able to deliver much larger currents on demand.
How does a DC power supply regulate voltage?
Many simple DC power supplies regulate the voltage using either series or shunt regulators, but most apply a voltage reference using a shunt regulator such as a Zener diode, avalanche breakdown diode, or voltage regulator tube. Each of these devices begins conducting at a specified voltage and will conduct as much current as required to hold its terminal voltage to that specified voltage by diverting excess current from a non-ideal power source to ground, often through a relatively low-value resistor to dissipate the excess energy. The power supply is designed to only supply a maximum amount of current that is within the safe operating capability of the shunt regulating device.
What is the drop out voltage of a linear regulator?
All linear regulators require a higher input than the output. If the input voltage approaches the desired output voltage, the regulator will "drop out". The input to output voltage differential at which this occurs is known as the regulator's drop-out voltage.

Why is a current regulator needed for a generator?
This would overheat the generator, so a current regulator is incorporated to prevent premature failure.
What happens when a field circuit is closed?
When the points are closed the field circuit takes the "easy" route to ground but when the points are open the field circuit must pass through the resistor to get to ground. The field coil on the generator is connected to one of the voltage regulator contact points. The other point leads directly to ground.
How fast does a Zener regulator work?
