单相集成车载充电器的充电控制

Charge Control of Single-Phase On-Board Integrated Battery Charger

主要研究基于六相永磁同步电机的单相车载充电器的充电控制。介绍了基于六相永磁同步电机的单相集成车载充电器系统,分析了该充电器充电过程中电机静止不转的原理。为了实现电流有功分量和无功分量的分离,对电机三相绕组中同相位的电流进行移相和坐标变换,得到旋转坐标系下的电流分量,设电流无功分量的参考值为0,实现充电器的单位功率因数的运行。仿真结果证明了该控制策略的可行性。

Charger control of single-phase on-board integrated battery chargers for EVs based on six-phase permanent magnet synchronous machine was presented.Single-phase on-board integrated battery chargers system was introduced.Principle of that the machine stays at standstill during charging process was analysed.To separate active and reactive component of current,phase of current in phase of three-phase winding was shifted,the current was transformed to rotational coordinate system.To make the charger operate in unity power factor,the reference of reactive component was set to zero.The simulation results verify the validity of the proposed control strategy.
