The Result of a Simulation :

Charging 100J from 60V to 700V with a 240V Supply

  --  1. Green : The Supply Current @ 240V / 50Hz , the I_max_eff is <= 2,5 A
  --  2. Red    : The View of the rectified Power Supply Voltage

  --  3. Blue   : The Voltage of a 400 uF Condensor 60V .... 700V

  --  The Start-Time is 0 mS , the Stopp-Time is 150mS
