DC 3.7V to 400KV Step up Power Module High Voltage Generator

The DC 3.7V to 400KV Step up Power Module takes a small battery-level input and produces a powerful high voltage output of up to 400kV. A 400kV high voltage generator like this uses a flyback transformer (a coil-based circuit that stores and releases energy as sharp pulses) to multiply input voltage many times over. The output appears as high-frequency DC arcs.

The high voltage booster runs on 3.7V to 7.4V DC, which means a single 18650 lithium cell powers it directly. One non-obvious fact: the copper coil inside heats up during extended use, so the working mode is continuous only with proper cooling in place. The honest trade-off is that the output voltage of up to 400kV is approximate and varies with input voltage and ambient temperature.

The high voltage generator works standalone without any microcontroller. Engineer and hobbyists working on electric arc and plasma demonstrations use it most. Connect 3.7V to 7.4V DC to the input wires, keep output terminals clear of skin and conductors, and the arc appears immediately. StemVolt provide  tested for visible output before dispatch.
