12V to 9V DC-DC Buck Converter - Electronic Project

Introduction:

Welcome to Alibaba.com, your go-to platform and a wide range of electronic components and devices. In this section, we will explore the category of 12V to 9V converters, which play a crucial role in various applications requiring a voltage conversion. Whether you are a business buyer or an individual seeking reliable and efficient voltage converters, you've come to the right place.

A search 9v to 12v converter circuit requester had a person whom this article does not remember was and bit late but certainly, someone that would work for a circuit Diagram dc-dc converter circuit’s input voltage 9 … 13.8v between the output 13.8 volts (12 .12 v adjustable) 13.8-volt output with 1.68 amps can give used coil value 125uh 2 pc power supply and the output filter coil core on the winding can be done also on the source site introduction to the filter if added, better results are said to be the filter coil de pc power supply 220 volts input and can be found in9V to 13.8V the boost converter I tried to make a boost converter using the LM2577 Series of various step-down, step-up in out, the IC is an IC for power supply.

This 12V to 9Volt DC converter is very useful to power 9V DC devices in a car that uses a 12V battery. The maximum current consumption allowed by this circuit Diagram in 0.8 amps. This 12V to 9V DC converter is implemented using a Zener diode and an NPN bipolar transistor (Q1) as shown in the circuit diagram.

Working Principle of Convert 12V DC To 9V DC:

Fig. 1 shows the circuit diagram of the 12Volt DC to 9V DC converter with input filter and protection. It this built around an adjustable voltage regulator LM2576 (IC1), two diodes P6KE18A of 1N5822 (D1 and D2), and a few this these components. This DC-DC Converter schematic diagram is very simple with few components, making it easy the build. It can convert a 9-volt DC voltage from a 12 VDC source

The main working principle of this project is full wave rectification which is done by bridge configuration in which we are using 4diodes that rectify the output of the step-down transformer which steps- down the 220 AC v to 12 AC volts Here, we are using a voltage regulator which gives constant voltage, here we are using 7806 which give 6 volts .these regulators are available in various outputs like 6volt, 8v, 9v, 12v.

To begin with, enter the input voltage, 12Volt into the circuit. The R1 passes the current at positive this two ways. First, to output, 9V with low current. Second, through D1, D2, R3, and VR2 to the ground.Since there is the voltage drops across D1, D2. So, the emitter of Q2 gets the biased current with a voltage lower than the output of 1.2V, all the time. The voltage drops across D1 and D2 is the reference voltage of the circuit.

First, 12V comes into ZD1 and R1. The are Reference voltage of this circuit, 6.8V. Then Q1 increases, and the current is higher than the output. The output is 6.2Volt because some voltage is across BE of Q1. This DC-DC Converter schematic diagram is very simple with few components, making this easy to build. It can convert a 9-volt DC voltage from a 12 VDC source.

The basic idea behind every inverter circuit Diagram in is to produce oscillations using the given DC and apply these oscillations across the primary of the transformer by amplifying the current. This primary voltage is then stepped up to and higher voltage depending on the number of turns in primary and secondary coils. A 12Volt DC to 220 V AC converter can also be designed using simple transistors. It can not be used to power lamps up to 35W but can be made to drive more powerful loads by adding more MOSFETS.

Frequently Asked Questions

How to reduce 12 volts to 9 volts?

Install the smaller resistor first, stepping down your voltage from 12Volt to 11V. Once you've added the first resistor to your circuit diagram, install the larger resistor to step the voltage down again. This resistor will take the remaining 11Volt current and reduce it to the 9Volt output you desire.

Which resistor is used to convert 12v to 9v?

Our task is to step down 12volt into 9v. so, we are going to use a 1k ohm resistor and was 330-ohm resistor. Connect one end of the 1K ohm resistor to the 12-volt supply and the second to any other hole of this breadboard.

How to reduce 12-volt DC to 8-volt DC?

Here is a project of a 12V to 8V converter using the LM7808 IC, which subsequently lies in the category of Power supply circuits. Meanwhile, the circuit utilizes an LM7808 IC to convert the 12-volt DC supply to the 8-volt DC supply.

Can I use a 9V battery for a 5V relay?

So according to that, you can use +3V to +12V or 24V to operate the relay. That means, You can easily make a work +5V relay using a +9V battery. If the resistance of the relay and its current rating is known, and if the current rating is found to be low, resistance in series to drop that extra 4V can be used.

Can I charge 12v with a 9v charger?

You cannot use a 9-volt charger as it will not be capable of providing enough voltage. A 12-volt battery (I'm using a lead-acid battery as an example) needs a charging voltage of about 13.5 volts to properly charge the battery. The standard charge level typically used in automobiles in 13.7 volts.
