Zero current switching high frequency isolated Dc-Dc converter

It's been a challenging task to distribute power in subsea oil and gas stations. In such high power applications ZCS based converters are more preferable as it uses switches like IGBT, GTO etc. This paper deals with the zero current switching full bridge dc-dc conversion. At the input side each modules are connected in series and at output side all bridge connections connected parallel. Input side inductances and output capacitances minimize ripple contents present in the system. The proposed system minimizes the losses due to diodes in the output side by replacing switches and also provides flexibility in the output voltage.
