  • Single phase single stage bi-directional level 1 electric vehicle battery charger
    Patent number: 11323038
    Abstract: A single phase single stage level-1 electric vehicle (EV) battery charger can control the power flow in both directions. The converter efficiency is high as the devices undergo ZCS which reduces switching loss in the devices. This converter does not require any intermediate DC link capacitor stage and the power density of the converter is high.
    Type: Grant
    Filed: August 2, 2018
    Date of Patent: May 3, 2022
    Assignee: UNIVERSITY OF HOUSTON SYSTEM
    Inventors: Kaushik Rajashekara, Parthasarathy Nayak, Sumit Kumar Pramanick
