11 VFD Power Supply Methods

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

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

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

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

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

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