RESONANT CONTACTLESS ENERGY TRANSFERWITH IMPROVED EFFICIENCY

Platform : EMBEDDED

Resonant Contactless Energy TransferWith Improved Efficiency

 

              Energy converters acquired nowadays highly improved performance, i.e., higher switching frequency, higher power density, improved safety, smoother operation and higher reliability, and last but not least, a maximized efficiency for the whole range of operation. The efficiency is one important reason why the resonant and especially, series loaded series resonant (SLSR) power converters are constantly gaining popularity .Their capabilities for soft-switching, high-frequency operation, minimized volume and weight, result in low maintenance cost, high reliability and highest efficiency.  

 

 

 

OBJECTIVE

 

  • To propose a new method for modeling and analysis of the SLSR converter used for contactless applications. The model consists of two separate equivalent circuits derived from the complete (i.e., more complex) equivalent circuit. Those two equivalent circuits represent the approximated behavior of the primary and the secondary sides of the converter.
  • The approximation’s aim is to obtain structures of the circuits similar to the idealized equivalent circuit considered.
  • To discover and analyze the influence of the loosely coupled transformer on the SLSR power converter performance, optimizing for the best possible efficiency.

 

             The input rectifier converts input ac supply in to dc supply with ripples. Hence the output of input rectifier is impure form of dc which is likely to be converted in to pure form of dc. That is given to the high frequency inverter which converts the impure form of dc in to high frequency ac with some higher order harmonics. Because the lower order harmonics are eliminated by PWM control. Then the output of high frequency inverter is given to series resonant circuit ,at resonance condition inductive reactance is equal to capacitive reactance then the Z=R, at this condition we can  obtain pure form of sinusoidal ac. Then that the pure form of ac is given to output rectifier through isolation transformer to obtain pure form of dc.
