Abstract :
This paper presents a new hardware embedded current control PWM named ldquoiPWMrdquo, which was developed based on current hysteresis PWM. iPWM generates PWM signals to the inverter using current deviation vector derived from current feedback and current reference. It is expected that the iPWM can improve performance of inverter. This paper explains the outline of iPWM and experimental results of permanent magnet synchronous motor (PMSM) drive.
