Reactive Power Control Strategy in Bidirectional AC/DC Converters with Enhanced Power Density for EV On-Board Chargers

Electric vehicles (EVs) are hailed as the future of transportation due to their eco-friendliness and superior performance. To support the growing EV market, governments and manufacturers have focused on developing incentive policies and charging infrastructure. From (3) it is clear that the instantaneous power $p_{c}(t)$ has two components: one is the average power and another one is the ripple power at twice of the grid frequency. The proposed system reduces voltage ripple and capacitor size, enhancing power density. The efficacy of the proposed control approach has been demonstrated by mathematical modeling, control strategy, design technique and simulation results. This research contributes to efficient and reliable on-board chargers for EVs, supporting the future of electric mobility.
