REFRIGERANT COMPRESSOR DRIVES OFFERING ENHANCED ROBUSTNESS, EFFICIENCY AND RATED VOLTAGE OPERABILITY |
摘要 |
Apparatuses, methods, and systems offering enhanced robustness, efficiency and rated voltage operability for refrigerant compressor drives are disclosed. An exemplary embodiment is a method of operating a variable frequency drive. The method includes operating the drive over a first operating range to provide at least a desired operating speed and minimize d-axis current, operating the drive over a second operating range including injecting d-axis current to provide at least the desired operating speed, operating the drive over a third operating range at a de-rated speed less than the desired operating speed. In the first operating range the drive input voltage is greater than a first value. In the second operating range the drive input voltage is lower than the first value and greater than a second value. In the third operating range the drive input voltage is lower than the second value. |
