ABSTRACT:
A current detection method for current detection of an output of a PWM inverter utilitizes current sampling at the timings of two zero vectors of the PWM inverter and selecting the sample value least influenced by noise as the detected current sample value and, when a time difference between the two vectors is large, an average value of the two sample values is selected.
