Design and fabrication of compact fluorescent lamp igniter using TRIAC-assisted high-voltage DC source

摘要

A potential approach for designing and fabricating igniter for compact fluorescent lamp is introduced using high-voltage DC (HVDC) source which is controlled by gate pulse obtained from TRIAC-based firing circuit. The Cockroft–Walton voltage multiplier circuit is used to design HVDC (2 kV) source where initially optimal rating of capacitance for each stage was considered based on experimental analysis. This design was further simulated by Multisim 11 and characterised experimentally. The response obtained by this method reveals that the HVDC source is able to ignite the fluorescence lamp potentially than the conventional available ignition processes. The major advantages of using HVDC are lower power to ignite fluorescence lamp, longer life and cost effective.
