💡Parts specifications:

Zener Diode (X)
simply change the zener diode value to get any other desired output voltage.
Using a 15V Zener diode, the output voltage will be around 14V.

If you need a lower output voltage, you can use a 12.6V Zener diode.

For use with 6V motors, you can also use a 6V Zener diode or a higher voltage one.

all resistors are 1/4 watt 5% CFR

bridge Diodes: for bridges you can also use 10amp bridge diodes or four 6a4 or 6a10 rectifier diode

For the capacitor, it is recommended to use a 1000 microfarad, 50 volt capacitor. (I used 2200uf)


💡Additional Explanation:

How does the circuit work efficiently without significant power loss?

The following voltage regulator circuit for motorcycles is designed to have very low power loss and high efficiency. This is achieved because the output transistor switches ON only during moments when the AC cycle peaks are close to the desired DC output voltage.

The presence of two transistors, BC547 and BC557, ensures that TIP147 remains OFF as long as the AC waveform voltage is above the breakdown voltage of the zener diode.

As long as the AC waveform voltage stays above the zener breakdown voltage, the zener diode remains conductive, which keeps BC547 and BC557 fully turned ON. In this condition, BC557 short-circuits the base and emitter of TIP147, preventing it from turning ON and making it non-conductive.

Whenever the AC waveform voltage drops below the zener breakdown voltage, the zener diode stops conducting, causing BC547 and BC557 to turn OFF. This removes the short circuit from the base and emitter of TIP147, allowing it to switch ON completely. At this point, the instantaneous voltage at the emitter of TIP147 quickly reaches the 1000uF capacitor, charging it while simultaneously supplying the required DC power to the connected load.

As the waveform voltage continues to rise back above the zener breakdown threshold, the zener diode, BC547, and BC557 turn ON again, switching TIP147 OFF. This cycle repeats continuously.

As you can see, TIP147 switches ON only when the peak AC voltage is close to the required output voltage. In any linear regulator, when the input voltage is close to the output voltage, the device runs cooler, dissipates minimal heat, and operates with higher efficiency. This design makes the voltage regulator extremely efficient.
