-High voltage reduction performed by a fixed ratio transformer (not a switch mode power supply)
-Simple bridge rectification with 330uF capacitor
-CD451BE Texas Instrument cycle counter used to provide timing via RC circuit (not dependant on 50Hz)
-No voltage regulator downstream of the transformer (i.e. voltage supplied to the charging circuit is dependant on input voltage)

good thing im taking electronics @ Niagara college, or else I wouldnt know what all that stuff meant.
