Method and apparatus for compensating for device dynamics and voltage drop in inverter based control systems |
摘要 |
A method for mitigating current distortion on inverter supply lines that supply a load with power from a PWM inverter, the inverter including a switch and diode bridge constructed using devices that are characterized by losses that cause current distortion, the invert, lines and load together characterized by inductive and capacitive dynamics that also cause line current distortions, the method including identifying both a device drop error due to device operating characteristics and a system related dynamics error due to interaction of system components and using those errors along with a more conventional dead time compensation scheme to modify modulating waveforms used in PWM comparison by a controller.
