Abstract: This paper proposes BKY converter, which is made to run in continuous conduction mode during both the charging and discharging cycles for low power EV applications. An analysis is conducted on the converter’s dynamic behaviour, and an approach to control is put forth to manage the power transfer between the traction system and battery in an electric vehicle. The suggested converter is designed using an extracted small-signal model. A significant ripple in the detected current causes switching instability in the current-mode control approaches at low duty ratios. The lowpass filter in the proposed average current mode control is positioned in the current loop’s feedback to suppress any high-frequency ripples. A computation delay occurs when the controller is implemented in the microcontroller. The control algorithm’s design takes this into account. A theoretical framework for current and voltage loop gain transfer functions are created using the realistic parameters of a BKY converter. Further, transient analysis is performed and validated by simulations.
