FIELD: microwave-operated lighting fixtures and their power supplies.
SUBSTANCE: proposed power supply designed to feed electrodeless microwave-operated lighting fixture has high-voltage transformer that functions to transform standard ac power into high-voltage ac power and to supply this high-voltage ac power; voltage doubling unit used for converting high-voltage ac power into high-voltage dc power, for doubling dc current frequency, and for supplying dc power at high frequency. Power is supplied to magnetron at higher frequency for eliminating flicker effect.
EFFECT: enhanced stability of light emitted into environment.
