Electronic switch i.e. pulse width modulation-dimmer, for switching and regulating power of e.g. fluorescent lamp, has switching device with electronic switching element interconnecting bridge circuit to segment current or power source

摘要

The switch has an electronic switching device including an electronic switching element e.g. insulated gate bipolar transistor (IGBT), interconnecting a bridge circuit for segmenting a current or power source. The switching element includes a sensor for determining a light ratio for regulating a switching gradient applying element e.g. microcontroller. The electronic switching device is connected in series to a consumer. The microcontroller controls the switch. A protective element of the microcontroller is interconnected by the regulator. An independent claim is also included for a method for operating a fluorescent lamp.
