High-frequency converter for fluorescent lamps using an improved trigger circuit

摘要: A high frequency converter for driving a gas discharge lamp load is comprised of an input stage receiving AC voltage and rectifying the to create DC source, oscillating power inverter, output connected trigger circuit used initiate oscillations in inverter. The further comprises ramp circuit. includes transformer having center tap two capacitors equal value from each end transformer. form resonant tanks. Also, RF choke may be between source voltage.
