Title:
Electronic ballast
Document Type and Number:
Japanese Patent JP6262135
Kind Code:
B2
Abstract:
The present invention discloses an electronic ballast for operating a gas discharge lamp which includes (i) a rectifier bridge circuit; (ii) a power factor correction (PFC) network that includes an electrolytic capacitor that charges by means of a circuit comprised by an inductor, diode and capacitor; and (iii) a switched inverter circuit that converts rectified DC voltage to a high frequency current AC voltage. The electronic circuit has a switch that switches on the aforementioned electronic elements making the (PFC) circuit consume energy continuously from the network, while the electrolytic capacitor remains connected to the voltage of the rectifier bridge, through the inductor and the diode, even if the inductor has no energy stored. From the storage capacitor the inverter is powered by a constant voltage and noise-free, allowing the inverter to power the luminous load properly.
