DC Power Supply 9 volt using TIP31 transistor

This is a DC power supply circuit designed to regulate 9 volts and provide a current output ranging from 1 amp to 2 amps. The circuit utilizes a modified TIP31 transistor, although alternative transistors such as TIP41, MJE3055, or 2SC1061 can also be employed effectively. The voltage can be adjusted between 6 volts and 12 volts using a variable resistor (VR1). It is essential to attach an appropriate heat sink to the TIP31 transistor to prevent overheating. The circuit also incorporates a BC182 transistor, which can be replaced with other compatible components. For achieving a stable positive voltage regulation at 9 volts, a 10-volt, 0.5-watt Zener diode is used. The circuit is designed to handle a current output of approximately 1 amp, supported by a 1-amp transformer and a 2-amp bridge rectifier. This mini power supply regulator is user-friendly and straightforward, making it suitable for various applications.

The described circuit serves as a reliable DC power supply capable of maintaining a stable output voltage of 9 volts while delivering a current between 1 amp and 2 amps, depending on the load and components used. The TIP31 transistor acts as the primary regulating element, with its performance enhanced by the addition of a suitable heat sink to dissipate heat generated during operation. The use of alternative transistors such as TIP41, MJE3055, or 2SC1061 offers flexibility in component selection, allowing users to optimize the circuit for specific requirements.

The variable resistor (VR1) allows for fine-tuning of the output voltage, facilitating adjustments between 6 volts and 12 volts as needed. This feature is particularly useful in applications where different voltage levels are required. The inclusion of a BC182 transistor in the circuit further supports the regulation process, with the option to replace it with other compatible transistors without compromising functionality.

To ensure a stable output voltage, the circuit employs a 10-volt Zener diode rated at 0.5 watts. This component is crucial for voltage regulation, as it maintains the desired output level by shunting excess voltage and preventing fluctuations. The power supply's design incorporates a 1-amp transformer, which provides the necessary input voltage while a 2-amp bridge rectifier converts the AC voltage to DC, ensuring that the circuit can handle the specified current output.

In summary, this DC power supply circuit is an effective solution for providing a stable 9-volt output with adjustable voltage capabilities, suitable for various electronic applications. The combination of well-chosen components and a straightforward layout makes this circuit accessible for both novice and experienced electronics enthusiasts.DC Power Supply 9 Volt Regulator, that can give current get about 1 Amp arrive at 2Amp. I sees part already modify transistor TIP31 and part come to can be usable well. By this circuit can give voltage 9 Volt at 1 Amp, be stable or can fine can decorate 6V to 12V with VR1 control. For Transistor TIP31, a friend can use other number all right such as TIP41, MJE3055, 2SC1061 etc. But must stick heat sink be appropriate with. The part BC182 use other number can replace get. The detail is other, see in the circuit. If you want positive voltage regulator 9Volt. I sizes beg for to suggest the nine s wander this, because it easy is good, the equipment is, seek easy with see the circuit has already. Friends must appear familiar certainly. It uses transistor ordinary just this, by friends use get many the number such as, 2SC1061, TIP41, MJE3055, etc.

And control voltage Regulator be stable at 9 Volt with Zener Diode 10V 0. 5watt. From this circuit can give current get about 1A, because of use Transformer 1Amp size and Diode Bridge 2Amp. For other detail, friends please see in the circuit better sir. Today I seeks mini power supply regulator give friends try out again. Be fixed voltage regulator 9V size. It uses transistor be pillar equipment perform boost up current tallly go up about 300mA. And by have Zener Diode perform steady voltage at 9Vdc. The detail is other a friend sees in the circuit please yes. 🔗 External reference
