Ballast and starter on conventional TL replaced by very practical and efficient electronic circuit with tiny size design. This electronic circuit based on electronic ballast control circuit for powering a fluorescent lamp which has a much better power efficiency than the ballast transformers. Starter component replaced by capacitor type.
Globally, this circuit content of a rectifier, DC to AC converter and starter capacitors.
Rectifier, convert 220 AC voltage into 320 DC (HVDC) voltage.
DC to AC Converter, change the 320 HVDC voltage to 500V - 800V AC voltage with frequency 20KHz - 60KHz.
