• A publication titled " Design, analysis, and implementation of a phase-shift controlled cascaded H-bridge and anti-interleaved zeta converter-based E-bike battery charging circuitry " has been published in the International Journal of Circuit Theory and Applications in May, 2024.

• A phase-shifted Full-Bridge based Zeta converter is designed to charge a 36V Li-ion EV (E-Bike) battery in the Constant Voltage(CV) mode and its hardware prototype has been implemented. The various tests are performed on the converter under specific constraints to check the effect of the phase-shift on the battery voltage and the optimized value
  of the phase-shift angle is chosen to charge the 36V Li-ion battery with the given specifications of the input voltage.
• The Sneak Circuits associated with an improvised variant of Full-Bridge based Zeta converter for the the EV battery charging application are analyzed and debugged. Based on the variation of the inductor currents under the different sneak-circuit phenomena, the
  methodology to eliminate the sneak-circuits associated with the converter has been formulated.
• An 800V, 22 kW On-Board Charger (OBC) with an intermediate DC-Link voltage of 400V has been designed. The schematics and the BOM of the designed system are developed. The various test plans were proposed and the whole system has been simulated in the environment of PSIM.
