Fluorescent lamp electronic ballast circuit one
Source: InternetPublisher:Lemontree Keywords: Electronic ballasts fluorescent lamps BSP Updated: 2020/10/03
(1) One of the electronic ballast circuits for fluorescent lamps
. The circuit is shown in Figure 2-11. This circuit uses the special thyristor SCR Y1112 for starting fluorescent lamps. Compared with ordinary thyristors
, it has a higher holding current value and a larger dU/dt value, which can ensure that the fluorescent lamp starts without flickering and has a long life.
