In this paper, an off-line voltage-fed single-switch zero-voltage-switching (ZVS) inverter is analyzed and designed for the filament power supply of cooker magnetrons. Due to the low resistance of cathode filament, an isolation transformer with large turn ratio is used. To obtain the ZVS operation, a parallel-resonant capacitor is connected to the...

... in Fig.1 is an example that the filament driving voltage decreases with the average anode current. Accordingly, as shown in Fig.2, besides the anode power supply (APS) a complete magnetron driver needs a separate filament power supply (FPS) to preheat and regulate the filament power. ...
