Abstract

Static power converters are used for many applications, like   frequency   converters   for   motors,   uninterruptible   power   supplies  (UPS’s),  general  power  supplies.  This  paper  analyses  the performance of high power static 400Hz supply system used in  aircraft  ground  power  units.  However,  the  problem  of  this  system  is  the  harmonics  coming  from  the  load  current  towards  the  supply.  This  problem  can  be  overcome  by  using  a  way  to  improve  the  supply  wave.  One  of  those  is  using  novel  polygon  transformer. This  paper  presents  combining  of  stabilized  powerAC-DC-AC  supply  using  polygon  transformer  to  improve  the  supply  wave  and  using  a  passive  filter  on  the  output  load.  The  design  and simulation of this system has been presented. In  [8],  the  polygon  transformer  is  connected  to  achieve  18-pulse AC-DC conversion through phase shifting between the two sets of voltages equal 20° with respect to the supply voltage. The disadvantage  of  this  connection  is  that  realizing  feasible  values  for  the  tapping  portion  for  step  up  operation  is  not  possible.  Therefore, in the proposed system, a novel idea for the 18 pulse conversion  is  achieved  by  phase  shifting  between  voltage  sets  with 40°.
