Abstract

The present invention provides an electric high frequency power supply, such as a ballast for a fluorescent lamp, and includes: a voltage doubler rectifier, two storage capacitors connected in series, and an isolation inductor between the rectifier and an AC input. Each storage capacitor is charged to an AC power input peak value. The inverter is connected to the storage capacitors, and a high frequency inductive load circuit is connected to the output of the inverter and a contact between the isolation inductor and the voltage doubler rectifier. A capacitor is connected from this contact to a contact of the two storage capacitors and, jointly with the inductive load circuit, form a high frequency resonance circuit. A current grabbed from an input AC power has impulses of the frequency of the inverter. The isolation inductor filters off the high frequency portion of the current impulses and makes the input current to approximate sinusoidal waves.
