There is a positive feedback relationship between the discharge current of the fluorescent tube and the on-resistance: when more current flows into the fluorescent tube, more gas is ionized, so that the on-resistance in the tube is continuously reduced, so that more current is generated. Into the fluorescent tube. If the fluorescent tube is directly connected to a fixed voltage power supply, the fluorescent tube will be burned quickly due to the rising current, so an auxiliary circuit is required to control the current entering the fluorescent tube at a fixed level, and this current control circuit is usually Known as the ballast. The ballast is actually an inductor. When the on-resistance drops to a very low level, the ballast's fixed inductive reactance and copper consumption cause the on-current to approximate a fixed value and start to work stably. Ballasts are divided into magnetic ballasts and electronic ballasts, in which the magnetic ballast needs to be matched with a small component called Starter (commonly known as "Starta") to make the differential pressure between the filaments The fluorescent tube is sufficient to discharge, while the electronic ballast does not require a starter because the starting work has been included in the ballast.
