The DC 3.7V to 400KV Step Up Power Module is a high-frequency high-voltage generator that accepts 3.7V to 7.4V DC directly from a single or dual-cell LiPo battery and produces high-frequency DC arc discharge up to approximately 400kV across the output wire leads. The 400kv high voltage generator uses a step-up coil design with plastic housing and copper winding to convert battery-level DC into high-frequency oscillating current, which the transformer steps up to breakdown voltage for the arc gap between the output leads.
this dc high voltage generator produces a high-frequency continuous arc that is maintained as long as the electrode gap remains within breakdown range and the input supply can sustain the current draw. The 400kv boost step up power module supports continuous operation when adequate heat dissipation is provided — the copper coil and driving transistor generate significant heat during sustained arc, and operating without a short duty cycle or active cooling will reduce module lifespan.
The high voltage generator module output leads measure approximately 10 to 12cm and the arc gap must be set by the user — shorter gaps produce more reliable arcs while longer gaps require higher atmospheric breakdown voltage and may not sustain reliably in humid Indian monsoon conditions. this 400kv Step up Power Module carries a severe electric shock hazard. Handle only with fully insulated gloves and non-conductive tools, and never contact the output leads during operation. Available from StemVolt, this module is suited for makers and developers exploring high-frequency high-voltage circuits.
