Figure 4 shows a plot of the half-bridge oscillation frequency as a function of time for all of the normal
modes of operation: Preheat mode, Ignition Ramp mode and Run mode. As shown in Figure 4 there
is an initial startup frequency that is much higher than the steady state Preheat mode frequency that
lasts for only a short duration. This is done to ensure that the initial voltage appearing across the lamp
at the startup of oscillation does not exceed the minimum lamp ignition voltage. If, at the initiation of
oscillation of the half-bridge, the voltage across the lamp is large enough, a visible flash of the lamp
occurs which should be avoided. This in effect is a cold strike of the lamp, which could shorten the
life of the lamp. Figure 5 shows the lamp voltage without the high initial startup frequency while Figure
6 shows the lamp voltage with the high initial frequency startup.
