The invention discloses a single-stage isolation type bidirectional vehicle-mounted integrated charging system for a new energy automobile, and belongs to the field of vehicle-mounted integrated charging. The problems that an existing two-stage isolation type vehicle-mounted charging system is large in size and high in cost and loss are solved. According to the single-stage isolation type bidirectional AC-DC charging and discharging topological structure based on three-phase motor winding reconstruction, aiming at a two-stage topological structure in the prior art, the size, the cost and the loss of the topology are further reduced, the system efficiency is improved, the single-stage isolation type bidirectional AC-DC charging and discharging topological structure has the advantages that the structure is simple, the cost is low, and the cost is low. In addition, the numerical value of the grid-side equivalent filter inductance in the charging and discharging mode can be increased, the motor does not rotate in the charging process, harmonic waves of the grid-side current can be suppressed, and the loss in the motor can be further reduced while the cost is reduced. The method is mainly applied to new energy automobile charging.

    新能源汽车用单级隔离型双向车载集成充电系统,属于涉及车载集成充电领域。解决了现有两级隔离型车载充电系统体积大、成本和损耗高的问题。本发明提出了基于三相电机绕组重构的单级隔离型双向AC‑DC充放电拓扑结构,该拓扑针对现有技术中的两级拓扑结构,在体积、成本和损耗方面进一步降低,提升系统效率,该单级隔离型双向AC‑DC充放电拓扑结构,还能够提升充放电模式下网侧等效滤波电感的数值,在充电过程中电机不发生旋转,能够对网侧电流的谐波进行抑制,减少成本的同时能够进一步降低电机内部的损耗。本发明主要应用在新能源汽车充电上。
