Figure 9.2 shows the VCO voltage, the voltage across the lamp, and the current through

the lamp during Preheat, Ignition, and Dim mode for 100% dimming level. Figure 9.3

shows these waveforms for 10% dimming level.

Figure 9.2: Preheat, Ignition, and Dim mode for 100% dimming level: CH1 is the VCO voltage, CH3 is

the lamp current, and CH4 is the voltage across the lamp

Figure 9.3: Preheat, Ignition, and Dim mode for 10% dimming level: CH1 is the VCO voltage, CH3 is

the lamp current, and CH4 is the voltage across the lamp
