  • Research And Development Within Piezoelectric Transformer (Pt) Based Converters Are Rapidly Increasi
  • As The Technology Is Maturing And Starts To Prove Its Capabilities
  • High Power Density And High Efficiencies Are Reported And Recently Several Inductor-Less Converters
  • Which Demonstrates Soft Switching Capabilities
  • The Elimination Of A Bulky Inductor
  • Reduces Size And Price Of The Converter
  • But Demands A Soft Switching Optimised Pt
  • Several Attempts Of Expressing The Soft Switching Capability Have Been Made [5][12]
  • With Some Shortcomings
  • The Goal Of This Paper Is To Derive A Simple Expression Of The Maximal Obtainable Soft Switching Cap
  • For A Specific Pt Design
  • Assuming A Matched Load
  • The Expression Has Been Derived Through Series Of Parametric Sweep Simulations Of The Inductor-Less
  • Which Revealed That A Linearization Of The Maximal Soft Switching Capability Can Be Performed
  • In The Area Of Interest
  • This Expression Is Intendedto Form A Basic Tool For Development Of Soft Switching Optimised Pt’S
  • Which Enables The Utilisation Of Inductor-Less Topologies
