摘要： 直流偏置型同步电机采用带直流偏置的正弦电流驱动电机运行,它特殊的相电流对功率变换器提出了特殊的需求。为降低功率变换电路的整体成本和系统体积,提高系统可靠性,开发直流偏置型同步电机使用的低成本高功率密度功率变换器非常迫切。提出了采用不对称功率器件布局的直流偏置型同步电机功率变换器,针对传统对称式布局功率变换器成本高、功率密度受限等问题提供了简单有效的解决方案。为了使各器件的功耗和温升更加平衡,提出了一种上桥臂采用高功率等级和下桥臂采用低功率等级功率器件的不对称双三相逆变器。通过理论分析确定了两组功率器件对应的功率等级,作为不对称功率器件的选型依据。结合仿真实验,对双三相直流偏置型同步电机功率变换器的功率器件电流等级以及散热布局的不对称特性进行了验证。证明了提出的不对称功率器件布局方式对降低电力电子器件的成本,增加系统功率密度,提升逆变器整体寿命具有重要意义。

Abstract: The DC-biased synchronous motor is driven by the sinusoidal current with DC bias. The special phase current puts forward special requirements for the power converter. In order to reduce the overall cost and system volume, and improve the system reliability, it is urgent to develop low cost and high power density power converter for DC-biased synchronous motor.A DC-biased synchronous motor power converter with asymmetric power device distribution was presented, and a simple and effective solution to the problems of high cost and limited power density of traditional symmetrical distribution power converter was provided. In order to make the power consumption and temperature rise of each component more balanced, an asymmetric dual three-phase inverter with high power level in the upper bridge arm and low power level in the lower bridge arm was proposed. Through theoretical analysis, the corresponding power levels of the two groups of power deviceswere determined as the basis for the selection of asymmetric power devices. Combined with the simulation experiment, the current levels of the power devices and the asymmetric characteristics of the heat dissipation of the dual-three-phase DC-biased synchronous motor motor power converter were verified. It is proved that the asymmetrical power device distribution is of great significance to reduce the cost of power electronic devices, increase the power density of the system and extend the whole life of the inverter.
