13KV High voltage power supply
This high-voltage power supply features an inverter circuit centered around Q1, which generates 150-V pulses for the converter SCR1 and capacitor C2. The output from component ?2 produces a 4.5-kV pulse, which is further amplified by a voltage-tripler network to...
Tesla Coils
The history of Nikola Tesla and Tesla Coils, how a Tesla Coil works, and an example of a homemade Tesla Coil. The homemade DIY Tesla Coil is battery-operated and has a gas plasma discharge terminal. Arcs can be made to...
0 1000 volt regulated high voltage
The input voltage for the high-voltage DC-DC converter is 12V AC at 800mA, which is then converted to DC using a 1A bridge rectifier diode. The output voltage of the converter can be adjusted within the range of 0-1000V DC....
