VFD Power Supply Methods

Power Supply Solution 1: Royer circuit Advantage: low component cost & high input voltage possible Disadvantage: custom designed transformer required

Power Supply Solution 2: For small Displays Advantage: only standard components required Disadvantage: higher component cost & max. 5Vdc input

Power Supply Solution 2: For small Displays (low voltage) LM9022 Voltage Multiplier for Anode/Grid voltage

Power Supply Solution 2: For small Displays (high voltage) LM9022 Advantage: only standard components required MC34063 Disadvantage: higher component cost & max. 5Vdc input

Power Supply Solution 3: For large Displays Anode/Grid Voltage Filament Voltage Advantage: only standard components required Disadvantage: higher component cost & max. 5Vdc input

Cut-off Bias Requirement (Ek) Background: Electron Leakage
