Mini High-Voltage Generator

Schematic Diagrams      Comments Off on Mini High-Voltage Generator

Here’s a project that could be useful this summer on the beach, to stop anyone touching your things left on your beach towel while you’ve gone swimming; you might equally well use it at the office or workshop when you go back to work. In a very small space, and… Read more »

Circuit Project: 12KV High Voltage Generator

Schematic Diagrams      Comments Off on 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… Read more »

Schematic Diagrams      Comments Off on 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… Read more »

High And Low Voltage Cut Off With Time Delay Circuit

Schematic Diagrams      Comments Off on High And Low Voltage Cut Off With Time Delay Circuit

Overview The power line fluctuations and cut-offs cause damages to electrical appliances connected to the line. It is more serious in the case of domestic appliances like fridge and air conditioners. If a fridge is operated on low voltage, excessive current flows through the motor, which heats up, and get… Read more »

Voltage Inverter II Circuit

Schematic Diagrams      Comments Off on Voltage Inverter II Circuit

This simple and inexpensive circuit can produce a dual (positive and negative) voltage from a single supply input. It is therefore extremely useful for powering opamp and other circuits that require a dual voltage from a single battery. The circuit will operate at an input voltage from around 5V to… Read more »
