DESCRIPTION:Abstract\n\nWe are envisioning future power grid systems with m
 uch higher penetration of distributed energy sources such as solar photovo
 ltaic arrays\, wind turbines and battery energy storage systems which are 
 essentially DC sources. Together with the proliferation of electric vehicl
 es\, rapid charging station and DC loads such as data centers\, DC-based g
 rid interfaces have also been given consideration. In this thesis\, an int
 ermediate bus converter for utilization in DC grid architectures that aid 
 the main AC power network is developed. The conceptualized power electroni
 c interface is a cascaded converter system resulting from the combination 
 of isolated full-bridge converter and active bipolar Cockroft-Walton volta
 ge multiplier. First\, preliminary investigations were performed to proper
 ly define the objectives and scope of the research. The study then involve
 d device-level\, converter-level and grid-level aspects of the converter d
 esign. In the device-level research phase\, the next generation Silicon-ca
 rbide power devices were studied for being a key component of the proposed
  converter. In the converter-level research phase\, the converter is confi
 gured for bidirectional capability and a design procedure is generated for
  calculating the main power component values. In addition\, reduced-order 
 modelling is performed to generate the system transfer functions for contr
 ol. Lastly\, for the grid-level research phase\, the converter is integrat
 ed into the renewable energy system. Case studies for the converter with i
 nverter-based resource operating in grid-following and grid-forming mode a
 re formulated to highlight the advantages of the proposed system over the 
 conventional solution. For solar PV systems\, it is shown that with the in
 tegration of the proposed converter\, it is possible to extract more power
  from the arrays\, which translates to better active power regulation. The
  study showed that a niche application where the proposed solution becomes
  attractive is in direct conversion from low voltage to medium voltage lev
 els\, eliminating the need for line-frequency transformers.\n
