Description
This work presents a hybrid power conversion strategy that merges high-efficiency digital DC-DC techniques with a universal single-stage DC-DC/AC converter for renewable and low-power applications. From the first concept, a digitally controlled buck converter employing a two-step digital PWM, Adaptive Window ADC, and Self-Tracking Zero Current Detector ensures ultra-low power consumption, minimized output ripple, and improved efficiency, making it suitable for IoT and energy-constrained devices. From the second, a dual-leg single-stage converter architecture enables seamless photovoltaic integration with both DC and AC grids, reducing redundancy through shared semiconductor structures and optimized protection circuits. By unifying these approaches, the proposed system enhances power density, conversion flexibility, and grid adaptability while ensuring reduced switching losses, minimized EMI, and stable operation under varying loads. Simulation and experimental validation confirm efficiency above 91% for low-power DC applications and up to 97% for PV-based grid operation, demonstrating strong potential in sustainable smart energy systems. 2025 IEEE.
