MOSFETS. Therefore, the ZVS inverter also contributes to reduced losses, reduced EMI
noise and a reduction in overall system heatsink requirements.
Output Circuit
The output filter is a single stage RC filter designed to keep ripple and output noise very
low.
Control Circuit
The control circuit handles all the functions associated with safe operation of the Xenon
lamp. Reliable lamp ignition as well as tight current regulation, overvoltage and over
power protection are controlled and monitored in the control circuit.
Auxiliary Power
All internal power supply requirements as well as the ex/-15V and +5V power
supplies are derived from the power factor control boost inductor. All auxiliary power
supplies are regulated by standard linear regulators.
Lamp Igniter Module
The igniter module provides the 40kV pulse required to break down the Xenon gas and
facilitate ignition. In standard configurations, the pulse is applied through the positive
output to the lamp anode. Power to the module is provided by the main power supply
chassis. Internal circuitry in the igniter module senses the presence of the high voltage arc
and briefly disables operation in the main power supply chassis in order to minimize
damage from high voltage noise.
