FPGA implementation of DSVPWM modulator

In this paper a novel field programmable gate array (FPGA) implementation of differential space vector pulse width modulator (DSVPWM) is presented. FPGA circuit was chosen because DSVPWM requires high computational power and its algorithms can be easily parallelized. The use of traditional sequential processor would need very fast and expensive hardware compared to the FPGA implementation. DSVPWM enables more accurate flux linkage formation than traditional modulators. DSVPWM is completely new modulation method and this paper presents its first implementation
