High Voltage Pulse Generator Electronic Circuit

Description: This circuit generates high voltage pulses from a 230 VAC line voltage. The drive end's swing comparator circuit was developed by the creator of this page. The working end is derived from a stroboscope trigger supply circuit. All circuits utilizing line voltage are inherently dangerous, and this one is particularly so. It is advised not to construct this circuit. When powered up, the circuit generates a fierce arc of 25 mm length between the coil's secondary. The waveforms depicted in the schematic were observed, and the output current was measured by allowing the sparks to ground through a 10-ohm resistor, with voltage measurements taken over the resistor using an oscilloscope. The triggering event control was observed between approximately 180 to 270 degrees of phase angle by adjusting the 470K potentiometer. A sheet of paper placed between the arc ignited immediately.

This circuit utilizes a high-voltage pulse generation mechanism, which is critical in applications requiring intense energy discharge. The primary component, a swing comparator circuit, operates by comparing input voltages and generating a controlled output that can drive a high-voltage transformer or coil. The design is based on a stroboscope trigger supply, which is known for its rapid pulsing capabilities, making it suitable for applications that demand precise timing and high energy.

The high-voltage output is capable of producing arcs up to 25 mm in length, indicative of the energy levels involved. The measurement of output current is performed by connecting a 10-ohm resistor in series with the output, allowing for the calculation of current through voltage drop observations using an oscilloscope. This method provides real-time feedback on the circuit's performance and allows for adjustments to be made to optimize the operation.

The control of the triggering event is achieved through a 470K potentiometer, which allows for fine-tuning of the phase angle between 180 and 270 degrees. This range is critical for ensuring that the output pulses are synchronized with the AC line frequency, thus maximizing the efficiency of the energy transfer.

Due to the high voltages and the nature of the circuit, safety precautions are paramount. The circuit should only be handled by individuals with appropriate expertise in high-voltage systems, and proper protective equipment should be used at all times. The circuit's design and operation highlight the importance of understanding the risks associated with high-voltage electronics, particularly in terms of potential electrical hazards and fire risks, as illustrated by the immediate ignition of paper placed near the arc.This circuit generates high voltage pulses from 230vac line voltage.
