Circuit Project: 12KV High Voltage Generator

The hobby circuit below uses an unusual method to generate about 12,000 volts with about 5uA of current. Two SCRs form two pulse generator circuits. The two SCRs discharge a 0.047uF a 400v capacitor through a xenon lamp trigger coil at 120 times a second. The high voltage pulses produced at the secondary of the […]


120 V to 12KV High Voltage Converter

Here is the schematic diagram of 120 V to 12KV power supply, or you may call it high voltage generator or 120V to 12KV converter. This circuit produce very high output voltage that is about 12K volt with very small current of about 5 microAmpere. Two SCRs form two pulse generator circuits. The two SCRs […]


High-Voltage LED Driver IC

High-Voltage LED Driver IC International Rectifier, IR®, a world leader in power management technology, introduced the IRS2980 high-voltage buck regulator control IC for LED light bulb replacement, LED tube lighting and other non-isolated LED driver applications. Rated at 600 V, the IRS2980 is the first in a family of high-voltage LEDrivIRâ„¢ ICs, and utilizes hysteretic […]


6V to 12V Converter Circuit

This inverter circuit can provide up to 800mA of 12V power from a 6V supply. For example, you could run 12V car accessories in a 6V (British?) car. The circuit is simple, about 75% efficient and quite useful. By changing just a few components, you can also modify it for different voltages. Circuit diagram Parts […]


10 mA 300V High Voltage Booster Circuit Diagram

The following circuit diagram shows a high voltage booster that produce 10mA output current. It will drive 350V into a 30k load as a positive-output-only circuit. Tubes with higher plate voltage ratings can extend the output capacity to several kilovolts even the circuit resulted in 350V limit. The booster output is fed back to the […]



12 to 120 Volt Inverter Circuit

Ever needed a low power 120volt AC power source for your car, van or truck? Well this circuit should do the trick for you. It will supply 15 watts of AC power to a device. It should power lamps, shavers, small stereos and small appliances. If you draw to much power the circuit will shut […]

IF YOU WANT TO BUILD IT YOU MUST ACCEPT THIS CONDITION. Using the procedures described above would prevent you from any damages/troubles. […]


12 Volt 30 Amp PSU Circuit

Using a single 7812 IC voltage regulator and multiple outboard pass transistors, this power supply can deliver output load currents of up to 30 amps. The design is shown below: Circuit diagram Notes: The input transformer is likely to be the most expensive part of the entire project. As an alternative, a couple of 12 […]


High Current Power Supply Circuit

Since my page was first posted, I have received a number of emails asking about a high current power supply. I looked around, but couldn’t find one that was suitable. So, I designed this. It is a linear supply, which might have a few of you rolling your eyes, but it takes very few parts, […]
