This report presents a novel three phase multi-phase boost chopper circuit with coupled inductor, which can achieve high power density performance in the power conversion system for electric vehicle. The proposed circuit which bring in a novel three phase coupled inductor core by using trans-linked technique can obtain the compact light-weight performance not only the output capacitor but also the magnetic component. The proposed core can output is about 2. 7 times as compared to the non-coupled inductor core in the continuous current mode drive, which is approximately equal to the total weight. The compact and light-weight characteristics and performance of proposed three phase multi-phase boost chopper circuit with coupled inductor is discussed with theoretical analysis and experimental results.
