DQ0 AND INVERSE DQ0 TRANSFORMATION FOR THREE-PHASE INVERTER, MOTOR AND DRIVE DESIGN

The disclosure relates to a test and measurement device and more specifically relates to the test and measurement device for a motor and a synchronous motor. The test and measurement device includes an interface configured to acquire analog three-phase signals from a device under test, and a processor programmed to execute instructions that cause the processor to perform a direct-quadrature-zero,DQ0, transformation and produce DQ0 signals based on the analog three-phase signals, and measure performance of the device under test based on the DQ0 signals. A method includes acquiring three-phasesignals from a device under test, performing a direct-quadrature-zero, DQ0, transformation on the three-phase signals to produce DQ0 signals, and using the DQ0 signals to measure performance of the device under test. 本公开涉及测试和测量设备，更具体地，涉及用于马达和同步电机的测试和测量设备。一种测试和测量设备，包括被配置为从被测设备获取模拟的三相信号的接口，以及被编程为执行指令的处理器，所述指令使得处理器基于模拟的三相信号执行直-交-零DQ0变换并产生DQ0信号，并基于DQ0信号测量被测设备的性能。一种方法，包括从被测设备采集三相信号，对三相信号执行直-交-零DQ0变换以产生DQ0信号，以及使用DQ0信号来测量被测设备的性能。
