Using variable-precision feedback to improve operational speed of the current loop in GaN-inverters

Using variable-precision feedback to improve operational speed of the current loop in GaN-inverters

With the advent of wide band-gap semiconductors like SiC and GaN, the frequency of pulse-width modulation has increased. In modern electric drives, the switching frequency can reach 100 kHz or more. In this case the performance of the drive is limited by the delay in the current feedback measureme...
