Here, a new bidirectional multi‐input‐multi‐output (B‐MIMO) high step‐up DC/DC converter with lower losses on switch/diode is proposed as suitable for electric vehicles. The proposed topology consists of five inputs and two outputs and the battery (energy storage) is considered one of the inputs. Due to the bidirectional nature of the proposed topology, different scenarios of it are described. In discharging mode, the stored energy of the battery is transferred to the output loads. In charging mode, the surplus energy by regenerative braking will be responsible for charging the battery in the related scenario. Also, each input can charge the battery separately in different scenarios. In general, the proposed topology is capable to work in different scenarios for bypassing/charging/discharging the battery. Other advantages of the proposed topology include continuous current of all the inputs, independent control of inputs from each other and lower normalized voltage stress on semiconductors. These features make the proposed bidirectional MIMO DC/DC converter (B‐MIMO‐C) suitable for electric vehicle applications. The proposed topology operation is provided in the laboratory testing for 870W prototype, and the obtained results confirm the theoretical calculations as well.

A coupled inductor based on dual switches buck-boost converter is proposed in the article, which can be used in renewable energy applications. Wide conversion ratio can be realized by regulating turns ratio of the coupled inductor and the duty cycle. The topology has a quadratic- like voltage gain, and the low voltage stress and current stress. Combing the passive clamping circuit to recover leakage energy, the voltage spikes of power switches are suppressed, improving the efficiency. Moreover, it has the merits of continuous input current and common ground. To demonstrate the superior performances of the presented converter, the principle of operation and steady-state analysis are presented in detail. At last, a 100 W experimental prototype was designed to verify the correctness of the theoretical analysis, with a maximum efficiency of 95.7% in step-up mode and 96.8 % in step-down mode.
