Paper Title - A Zero Current Switching Resonant Buck Converter
In this paper a zero current switching auxiliary circuit used for soft switching of DC-DC buck converter
is presented. Buck converters are high frequency dc-dc converters operating on PWM principle. The switching devices are
made to turn on and turn off the entire load current at high di/dt and withstands high voltage stress across them.
This propels the need for soft switching techniques which provides an effective solution and eliminates electromagnetic
interference. The proposed model of zero current switching(ZCS) resonant buck converter is simulated in matlab/
Simulink. The performance of the converter is improved by introducing PID controller and fuzzy logic controller. The
ZCS buck converter obtained has achieved improved efficiency along with reduced ripple output. The feasibility of
circuit is confirmed by waveforms that were found to be in precise proximity of the theoretical waveforms.
