Principle of fluorescent lamp ballast

Principle of fluorescent lamp ballast

The inductive ballast is composed of silicon steel sheet, enameled coil, frame end cover, bottom plate (housing), wiring terminal, etc. Inductive ballast is an iron core inductive coil. The nature of the inductance is that when the current in the coil changes, it will cause changes in the magnetic flux in the coil, thereby generating induced electromotive force. Its direction is opposite to the direction of the current, thus blocking the current The change of, so as to limit and stabilize the current.When 220V50Hz AC power is applied to the switch closed circuit, the current flows through the ...
