Due to their advantages of reduced cost, integrated multi-port converters (MPCs) with fewer components have received extensive attention. In this article, by extracting the concept of series/parallel input pulsating cells (IPCs) and output pulsating cells (OPCs), a set of syntheses for generating MPCs composed of IPCs and OPCs is proposed. When compared with the existing synthesis method for non-isolated MPCs, the proposed approach employs only one inductor and features single-stage power conversion between any two ports, which offers benefits in terms of compact size and high efficiency. Two design examples are shown to demonstrate the worth of proposed methodology. The operation principles are first analyzed. The pulsewidth modulation (PWM) and power control schemes are explained and designed in detail. To design the controllers, small-signal models for each of the operation modes are also extracted. Meanwhile, the characteristics of pulsating cells with different configurations are discussed and compared. The theoretical analysis is validated by simulation and experimental results for different operation conditions.

由于具有降低成本的优势，具有较少组件的集成多端口转换器（MPC）受到了广泛关注。在本文中，通过提取串联/并联输入脉动单元（IPCs）和输出脉动单元（OPCs）的概念，提出了一套由IPCs和OPCs组成的生成MPCs的合成方法。与现有的非隔离 MPC 合成方法相比，所提出的方法仅使用一个电感器，并且具有任意两个端口之间的单级功率转换，具有紧凑的尺寸和高效率的优点。展示了两个设计示例来证明所提出的方法的价值。首先分析操作原理。详细解释和设计了脉宽调制 (PWM) 和功率控制方案。为了设计控制器，还提取了每种操作模式的小信号模型。同时，对不同配置的脉动单元的特性进行了讨论和比较。理论分析通过不同操作条件下的仿真和实验结果得到验证。
