2. Abstract
• A pulse-width modulation modulator for a non inverting bidirectional buck–boost converter is
analyzed and a corresponding average-mode current controller design is revealed.
• The main feature of the modulator is the ability to create switching sequences for both converter
legs without requiring any information regarding either operation mode or the direction of power
flow.
• The modulator receives a control signal generated by the current controller, and a triangular
carrier and generates driving signals with two different duty cycles, allowing tight control of the
inductor current throughout the entire operating range.

4. Existing System
• Bidirectional converters are generally divided into isolated and nonisolated types.
• In the case where galvanic isolation is not required, a noninverting buck–boost converter is
probably the most versatile topology, supporting BUCK, BOOST, and BUCK–BOOST operations.
• The synchronous version of the converter allows bidirectional power flow.
• When a bidirectional noninverting buck–boost (BDNIBB) converter is voltage mode
controlled(utilizing either hard or soft switching, the controller and modulator must be carefully
designed to treat inherent nonlinearities and non smooth transients of mode transitions, which
occur if the BUCK–BOOST operation is skipped to improve efficiency.

5. Proposed System
• In this project, the modulator is generalized and extended to the average current-controlled
bidirectional BDNIBB converter.
• Comprehensive analysis of the modulator operation is carried out and current controller based on
the proposed modulator is designed.
• It is shown that when the propose modulator is adopted, the control-to-output transfer-function
gain of the current loop remains unchanged upon mode transitions and the corresponding plants
differ only in terms of disturbance.
