12V to 300V DC-DC converter circuit

This is a 12v to 300v dc-dc converter circuit using  2N3055 transistors and 2N1305 are pillar equipment and power transformer transform the sky tallly go up then change voltage regulator rectifier with diode and Capacitors make output have voltage about 300V at Current 55mA. With this circuit a friend can apply the work next. Request have fun , DC Power Supply 300V or DC Converter 300V.

DC Power Supply 300V From battery 12V

The following circuits to similar to the this circuit.

This circuit is DC to DC Inverter. It can increase DC Voltage of Battery 12V to be DC High Voltage 300V. But this circuit has a low current.

Then, build easily and use general components such as the Transformer the general also the work. And the integrated circuit, transistors.

IC 555 is A stable Multivibrator that performs a Square wave Frequency Oscillator or pulse generator go out at pin 3. It makes Q1 and Q2 work alternate. To send the electric power goes to Transformer. And change to high voltage output.

Next, the AC high voltage comes to the rectifier circuit has DCV 300V output.

The Q1 and Q2 should are held heat sink.

The detail of others, Please see in the circuit which not difficult. Have fun Cheap high Voltage Low Current DC to DC inverter Circuit

    “…transformer transform the sky tallly go up…”? Seriously?

    This looks like it could be a great, helpful website, if only the text made sense. If you’re going to write the text in English, could you please work with someone who knows the language to edit for you? I have no idea what you’re trying to say here.

    Hi i need circuit to step up my dc motor fuelless generator. 1.5v to 5 or 6v. Or a circuit that i will use to connect two dc generator together to step up volt that will charge my phone and feedback the generator battery. Please reply me to my e-mail. Thanks.

    He mean if u build this project and its done…U curcuit board will trust to the sky like firecracker…prakkkk….up to da sky..am i right?

    Good Day, Thank you for the nice collection of projects.

    I want to use your DC-DC converter to drive a DC vacuum tube amplifier, I just need a little more power out of it – 150mA, would it be possible to just use a bigger transformer? or should I add another set of 2N3055 transistors in parallel to the existing ones with 1ohm bleeder resistors on them?

    Thank you

    what changes should be made to allow load current of about 3-4 A?

    • Hello Nafis Ahmed,
      Thanks for your visit. I am deeply sorry. This circuit, I haven’t tried it yet. Therefore cannot recommend you And in this circuit, the concept of it gives very little current.

      However, I believe that you will be able to build this circuit with an output current of 3A.

      Thanks
      Apichet
