According to the abstract released by the Intellectual Property India: "A new power conversion device and its control method are introduced. The device has a single, magnetically coupled unit that combines boost, active power-decoupling (APIC), and flyback stages. This makes it possible to have high voltage conversion ratios and galvanic isolation. The proposed system is designed for regenerative braking in electric and hybrid vehicles. It lets power flow in both directions between the main battery, auxiliary storage, and high-voltage DC bus, all without needing separate conversion stages. Finite-control-set model predictive control (FCS-MPC) is used to control the system. At each time step, it predicts how the system will behave for all possible switch positions and picks the best one based on a cost function. This function looks at the stability of the output voltage, the accuracy of the current tracking, the ripple across storage devices, the switching losses, and the charge imbalance. Each of these factors is given a different weight in real time. When the car is braking, the system focuses on quickly capturing energy, and when the car is driving normally, it focuses on being efficient. The method gets rid of pulse-width modulation, linear compensators, and traditional PI control loops by letting you choose switching states directly. This makes the processor work less and respond faster. Compared to standard multi-stage converters, the integrated converter design has fewer passive parts, is smaller overall, and has a higher power density. Tests on prototypes and simulations with hardware in the loop show that this is a small and effective solution for modern electric drivetrains and hybrid energy systems. It improves voltage recovery, reduces overshoot, and gets more energy back after braking."
