Abstract
An igniter circuit () for an HID lamp () has a DC input (VBUS) for coupling to a source of DC voltage, and an output () for coupling to the HID lamp. A resonant ignition circuit () operating at a controlled resonant frequency is coupled to the DC input for producing successive bursts of voltage having a frequency equal to the resonant frequency and having an amplitude that increases with time. The resonant ignition circuit () feeds the bursts of voltage across the output of the igniter until an HID lamp coupled thereto reaches breakdown.
