控制棒驱动机构的磁力线圈通常由电动发电机组通过半波整流供电，因此供电回路中含有大量的直流分量和高次谐波，对发电机的运行造成不利的影响。本章针对该供电方式，对发电机定子绕组采用星形和曲折星形连接方式的谐波磁势进行了全面分析，从理论上验证了曲折星形连接能有效降低电机损耗及磁路饱和的可能性，同时也提出了在曲折星形连接方式下减少5、7次谐波磁势和偶次谐波电流的建议，其分析结果能够为棒电源系统的优化设计提供理论依据。

The control rod drive mechanism coils are generally supplied by the motor generator set via half wave rectifier, so there are a lot of direct current and high harmonic wave component in the power supply circuit, which will have adverse influence on generator operation. The paper provides detailed analysis of the harmonic MMF for the generator stator winding using the star and Zig-zag connection based on this power supply mode, also validate Zig-zag connection can effectively reduce generator wastage and possibility of magnetic saturation in theory, and offer a proposal to reduce five/seven harmonic MMF and even-order harmonic current for Zig-zag connection mode at the same time. The analysis result can provide theory basis for the CRDM power supply system optimizing design.
