## 6 Applications
Considering that the aim of controlling the _EVBC_ is to integrate _EVs_ into smart grids, discussions and evaluations are based on the grid-to-vehicle (_G2V_) and vehicle-to-grid (_V2G_) modes of operation. \\ \hline \multirow{9}{*}{Five-level Cascaded H-bridge _LCC_ Resonant Converter.} & \multirow{9}{*}{X-ray applications} & High voltages are needed in many medical and industrial applications, such as X-ray generation and electron beam welding; these applications also require large power variations. Regarding X-ray applications, the power available to the X-ray tube normally varies significantly (\(<\)1 kW-100 kW) based on the employed radiographic technique or the type and thickness of the material. A new _LCC_ multilevel topology has been proposed to solve the problem that distinguished radioscopy from fluoroscopy. Fluoroscopy requires long-time exposure to low-power radiation, while radioscopy involves short-time exposure to high-power radiation. Regarding the fact that the converter design should consider the maximum power range, the efficiency will be poor when working at low power levels. This problem can be addressed with the proposed new topology. \\ \hline \multirow{9}{*}{Half-bridge Boost Bidirectional _LCC_ Resonant Converter.} & \multirow{9}{*}{Microgrid application} & A non-isolated soft-switching bidirectional _DC/DC_ converter for interfacing energy storage in a DC microgrid has been offered. The proposed converter incorporates a half-bridge boost converter at the input port, an _LCC_ resonant tank to aid in soft-switching switches and diodes, and lastly a voltage doubler circuit at the output port to double the voltage gain. Additionally, the _LCC_ resonant circuit provides the converter with a proper voltage gain. Thus, the converter’s overall high voltage gain is achieved without the use of a transformer or a large number of multiplier circuits. \\ \hline \multirow{9}{*}{Two Three-level Full-Bridge _CLLC_ Resonant Converters.} & \multirow{9}{*}{Off-board _EV_ charger} & A novel three-level _CLLC_ resonant converter for an off-board _EV_ charger has been suggested in order to accomplish bidirectional power transmission between the _DC_ microgrid and the _EV_. The proposed converter adapts to the wide voltage range of _EVs_, from 200 to 700 V, by inserting resonant _CLLC_ components and combining the working modes of the two three-level full bridges. Due to the totally symmetrical structure, this converter can work in two power directions, _G2V_ and _V2G_. \\ \cline{1-1}  & & \multirow{9}{*}{Off-board _EV_ charger} & A non-isolated soft-switching bidirectional _DC/DC_ converter for interfacing energy storage in a DC microgrid has been offered.
