The thesis is related to investigate characteristics and performance of a Z-source full
bridge dc/dc converter which boosts the input voltage to a higher output voltage. Zsource
structure increases the reliability of the converter according to current fed full
bridge dc/dc converter and also reducing the complexity according to two stage
design approach (boost followed by full bridge). Operating principles of the Z-source
dc-dc converter is described by current and voltage waveforms of the components
and mathematical expressions. Moreover, small signal models and transfer
functions are derived for both continuous current mode (CCM) and discontinuous
current mode (DCM) operations of the converter. Waveforms obtained,
mathematical expressions, small signal models and transfer functions derived are
confirmed by simulations. Performance of the converter and controller are both
tested in laboratory prototype.
