In a negative ion generator, the positive side of a high voltage source is grounded ... The red wire should arc to a pin on the flyback transformer. This pin is the ground, note its location.

[The LED Artist] often found a need for a relatively high voltage (100 to 200 Volt) but low current DC power supply, and it turns out that a small HV generator that uses a single AA cell only ...

Learn how to create a high voltage generator using a flyback transformer’s ferrite core. This step-by-step process involves assembling a circuit with MOSFET z44, tip122, or D880 to boost voltage ...

Cold ironing is the practice of shutting down a vessel’s generators ... high voltage brings with it a variety of unique safety considerations. One of the more important is the risk of arc ...
