Converters with High Internal Frequency

  • F. C. Schwarz
Part of the Earlier Brown Boveri Symposia book series (EBBS)


Continuing work on the development of the technology of electric-power converters in­dicates the desirability of relatively high internal operating frequencies in order to sa­tisfy a number of advantageous system characteristics. It appears desirable to equip these power converters with a number of properties which are summarized in the fol­lowing paragraph.
