摘要: In a voltage-source inverter AC power supply, the currents are measured exclusively by sampling DC current in link between and inverter. Each sample so derived is correlated to status of switches at instant sampling, or before after change switching This technique applies more generally pulse-width modulation applications, but also an adjustable voltage input (AVI) motor drive.
