Abstract: A novel high switching frequency universal space vector modulation (USVM) technique which dramatically reduces the online computation burden imposed on the processor, is presented for inverter applications. It is shown that this new technique significantly simplifies the implementation for high switching frequency applications of the USVM technique without causing performance deterioration with regard to harmonic distortion and fundamental voltage error. Furthermore, it is shown that the modifications necessary to reduce the PWM calculations using the new high frequency USVM (HFUSVM) technique can be easily incorporated into existing microprocessor or digital signal processor (DSP) implementations and therefore existing PWM controllers using USVM can be easily updated for high frequency inverter control. Experimental and simulation results are presented to confirm the theoretical developments.

Analysis and realization of a pulsewidth modulator based on voltage space vectors
TL;DR: In this article, a space vector concept for deriving the switching times for pulsewidth-modulated voltage source inverters is compared with the conventional sinusoidal concept, which results in lower current harmonics and possibly a higher modulation index.
