  • DQ0 and inverse DQ0 transformation for three-phase inverter, motor and drive design
    Patent number: 12088223
    Abstract: A 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-phase signals 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.
