Principle of electronic ballast
Electronic ballast is a type of ballast, which refers to electronic equipment that uses electronic technology to drive an electric light source to produce the required lighting. Corresponding to it is an inductive ballast (or ballast). Modern fluorescent lamps increasingly use electronic ballasts, which are light and compact, and can even integrate electronic ballasts with lamps. At the same time, electronic ballasts can usually have the function of a starter, so it can save money. Go to the separate starter. Electronic ballasts can also have more functions, such as improving or eliminating the flicker phenomenon of fluorescent lamps by increasing the current frequency or current waveform (such as a square wave); it can also make fluorescent lamps use DC power through the power inversion process. Some shortcomings of traditional inductive rectifiers make it being replaced by increasingly mature electronic ballasts.
The electronic control device that uses semiconductor electronic components to convert DC or low-frequency AC voltage into high-frequency AC voltage to drive low-pressure gas discharge lamps (sterilization lamps), tungsten halogen lamps and other light sources. The most widely used electronic ballast for fluorescent lamps. The electronic ballast adopts modern soft-switching inverter technology and advanced active power factor correction technology and electronic filtering measures, so it has good electromagnetic compatibility and reduces the loss of the ballast itself.
