This High Voltage power supply is able to generate up to 25-30kV DC Output from a 12-24v DC input. With a fully adjustable DC input power supply (0-24V/4A), it is possible to adjust the HV output between 5 to 30kV. This HV power supply use a common flyback driver circuit with two 2N3055 power transistors as a push-pull oscillator. A common flyback transformer from an old TV/monitor can be used, the transformer HV output is connected to a 30kv Voltage tripler which commonly used in all color TV monitors.
