During lamp ignition, the DC bus can drop below the rectified AC line voltage causing current to conduct directly from the output of the rectifier, through the PFC inductor and diode, to the DC bus capacitor. This results in a ...

Step 5: Program Maximum Ignition Current The maximum ignition current is programmed with the external resistor RCS and an internal threshold of 1.3 volts. This threshold determines the over-current limit of the ballast, which can be exceeded when the frequency ...
