本实用新型中，三重三相双向DC-DC变换可采用公知的结构。如图3所示，为三重三相双向DC-DC变换器的电路原理图，被测对象的汽车电机功率范围较大，所以采用三相三重半桥式结构作为变换主电路，可以有效减少谐波含量和电流的脉动率，减小被测电机驱动系统(被测对象)与测功机系统的相互干扰，同时优化能量回馈滤波器的总量和体积，使系统的结构设计达到最优。除此之外，三相三重的特殊结构使系统具有备用功能，某一单元发生故障时，其余单元可以继续运行，大大提高系统的可靠性。In the utility model, the triple three-phase bidirectional DC-DC conversion can adopt a known structure. As shown in Figure 3, it is a circuit schematic diagram of a triple three-phase bidirectional DC-DC converter. The power range of the vehicle motor under test is relatively large, so a three-phase triple half-bridge structure is used as the main circuit for the conversion, which can effectively reduce harmonics. Wave content and current pulsation rate reduce the mutual interference between the measured motor drive system (measured object) and the dynamometer system, and optimize the total amount and volume of the energy feedback filter to optimize the structural design of the system. In addition, the special three-phase three-layer structure enables the system to have a backup function. When a unit fails, other units can continue to operate, which greatly improves the reliability of the system.
本实用新型中，Matlab仿真系统和dSPACE半实物仿真系统均为公知常用的仿真系统。In the utility model, the Matlab simulation system and the dSPACE semi-physical simulation system are known and commonly used simulation systems.

Second, the load simulation tracking control system is used to realize the fast response and precise tracking control of the dynamometer system to the load simulation; finally, the comprehensive performance test and analysis of the motor drive system is realized through the performance analysis system. And the measured value of the measured object can be dynamically displayed in real time through the user management system of the industrial computer, and the test process can be controlled at the same time.
