Components Selection
The output inductor and capacitor values should be chosen to allow the ballast to run at
maximum brightness around 40-45kHz. This will minimize losses in the inductor. For
this example the IR Ballast Designer software * has been used to select the required
preheat, ignition and run frequencies for a 32W spiral CFL lamp giving an LRES of
2.2mH and CRES of 4.7nF.
Output Inductor Design
The output inductor LRES should be designed to allow a high peak ignition current
without saturating. This is important as the IRS2530D shutdown will be triggered if the
inductor saturates. The ignition current depends on the type of lamp being used and
must be kept to a minimum by ensuring the preheat is sufficient. To minimize losses in
the inductor multi-stranded wire should be used in combination with Ferrite cores of
adequate quality. The best approach to design is to wind as many turns as possible of
multi-stranded wire and have the largest gap possible to achieve the correct
inductance. This will produce the highest available peak current before saturating the
inductor. It is important to be aware that when the cores are hot the saturation point and
hence the peak current for the inductor will be lower therefore a poorly designed
inductor may result in the ballast shutting down during an attempted hot re-strike.
The inductor design process can be greatly simplified by using the Ballast Designer
software produced by I.R. For this application and lamp size it is recommended to fix
the core size to EF20.
