High Voltage Power Supply with Oscillator


 
(Select image for full-sized schematic)

Description

This circuit provides a variable, +65V, current limited, ~1.2A, power supply and includes an adjustable low frequency oscillator and drive circuit. The primary purpose of this project was to construct a device suitable for solid state Jacob's Ladder, plasma globe, and other high voltage (HV) experiments. Specifically, the intent was to treat each HV experiment as a plug in module utilizing this project as its solid state drive source.

Design Details -- How It Works

This project is comprised of six sub circuits -- many of which are described in the Circuits section of this website.:

  1. Unregulated DC Power Supply. Comprised of switch SW1, fuse F1, transformer T1, bridge rectifier BR1, power indicator LED D1, and associated current limit resistor R4, and filter capacitor C1. (A description of this circuit will be added to the Circuits section in a future update to the website.)
  2. 1.2A Current Limit.
  3. +12V Regulator with HV drive circuit.
  4. +65V Variable Supply. (A description of this circuit will be added to the Circuits section in a future update to the website.)
  5. Low Frequency Oscillator.
  6. HV Switching Circuit. Comprised of the HCPL3000 optocoupler U4, and the BU208D HV power transistor, Q9. (A description of this circuit will be added to the Circuits section in a future update to the website.)
