This paper presents a hybrid modulation technique combining phase shift control with sigma-delta based cycle skipping for asymmetrical bidirectional DC/DC converters. The proposed method enhances the light load efficiency while maintaining the precise power regulation through two independent control parameters. Unlike the conventional burst mode technique, the sigma delta approach enables continuous power regulation through dynamic cycle skipping modulation. Comprehensive numerical analysis validates the theoretical model, demonstrating significant efficiency improvements under light load conditions. Additionally, this technique establishes a foundation for talkative power converter applications, where the modulation pattern could enable simultaneous energy and data transfer without additional communication infrastructure.
