Abstract
A system for powering an excimer bulb includes a first inductor configured to be coupled to a first terminal of the excimer bulb. The system further includes a first transistor coupled to the first inductor and having an on state configured to allow current to flow through the first inductor and an off state. The system further includes a second transistor configured to be coupled to the first terminal of the excimer bulb and having an on state configured to allow current to flow through the excimer bulb and an off state. The system further includes a controller coupled to the first transistor and the second transistor, and to control operation of the first transistor and the second transistor to power the excimer bulb.
