FIGURE 1 - Typical Application
This diagram depicts a complete 250 Watt Preregulator. At full load, this preregulator will exhibit a power factor of 0.99
at any power line voltage between 80 and 260 V
RMS
. This same circuit can be used at higher power levels with minor
modifications to the power stage. See Design Note 39B and Application Note U-134 for further details.
NOTE: Boost inductor can be fabricated with ARNOLD MPP toroidal core part number A-438381-2, using a 55 turn primary and a
13 turn secondary.
