    Recent demands for high power density power converters operating at high switching frequencies has led to the introduction of resonant-mode technologies in power converter design. The author presents a discussion of the use of such technologies for off-line power conversion. Available off-line resonant mode techniques and topologies are given and the topologies are categorised according to their c... View full abstract»

    High frequency, off-line power conversion requires zero voltage switching (ZVS) topologies; such topologies generally fall into two categories. One circuit from each category is chosen and compared for LV output applications and observations on their relative merits made.<<ETX>> View full abstract»

    Laminar magnetics ease construction and eliminate creepage and clearance problems. However, these advantages are offset by power dissipation caused by the high frequency which they use. The author looks at the cause of winding loss within a magnetically poor planar transformer. Using laminar magnetics it is possible to minimise power dissipation so enabling the many advantages that can be gained f... View full abstract»

  • An on line high frequency series resonant converter

    Due to the advent of power MOSFETs, higher frequency operation to hundreds of kiloHertz has been made possible, and the series resonant topology has been reported to offer smaller size, improved reliability, and reduced electromagnetic interference. Hence high frequency resonant converters have become attractive to power supply designers. The author explains the basic operation of a full bridge, s... View full abstract»
