This invention presents a new method for controlling a non-inverting buck-boost converter using an FPGA with dynamic reconfiguration. Unlike traditional converters that use a single controller for both buck and boost modes, this approach uses separate controllers optimized for each mode. The FPGA adjusts in real-time: configuring only the necessary circuits for the current mode (buck, boost, or both). This not only improves efficiency but also reduces power consumption by up to 48%. The system ensures smooth transitions between modes, maintaining stable output voltage even during changes in input voltage or load. Overall, it represents a significant advancement in power electronics, offering better performance and energy savings.
