Interleaved Boost Based AC/DC Bidirectional Converter with Four Quadrant Power Control Based on One-Cycle Controller (OCC)

This paper presents a new bidirectional AC-DC interleaved converter topology and its control technique. The proposed control technique, based on One Cycle Controller (OCC), is used to process power in all four quadrants in the V-I plane. A fictitious reactive current is introduced in the control law that decides the PWM switching action. Further, a size reduction of the input side magnetics by the use of coupled inductors is proposed. The simulation and experimental results show a low THD content in the input current and a fast control of power factor, load and switch between modes of operation. The experimental and simulation results for a 2KW lab prototype are included in this paper which show a close match of theoretical and experimental results.
