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. 5Vdc 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 Advantage: only standard components required MC34063 Disadvantage: higher component cost & max. 5Vdc input
16
Power Supply Solution 3: For large Displays
Anode/Grid Voltage Filament Voltage Advantage: only standard components required Disadvantage: higher component cost & max. 5Vdc input
17
Cut-off Bias Requirement (Ek)
Background: Electron Leakage
