Design and implementation of controllers for contactless power transfer On FPGA

In this paper, design algorithms for implementing controllers for DC to AC converter and DC to DC converter using Field Programmable Gate Arrays (FPGA) are presented. We used DC to AC converter proposed in [1], which uses free oscillation and discrete energy injection technology for our experiments. For DC to DC converter, Cuk converter [2] was used in our experiments. The controller of DC to AC converter for different values of capacitors, for minimum switching losses on FPGA has been tested satisfactorily. The controller for DC to DC converter, to set the output voltage to a reference voltage irrespective of the input voltages has also been tested successfully.
