An approach to generate space vector PWM (SVPWM) waveforms for three-phase voltage-sourced inverters (VSIs) using a low-cost field-programmable gate array (FPGA) is presented. In the developed approach, the offline computations of occupied times according to various modulation index and phase angle are stored in EPROM, thereby allowing a microprocessor-free design. With the proposed configuration,...
This paper presents a novel circuit realization of the three-level space-vector pulse-width modulation (SVPWM) strategy. A simplified algorithm for the three-level SVPWM is proposed. Due to the geometrical symmetry of six sectors, there exist the close relationships in on time calculations and on time arrangement for switches between them. So it can complete the computation of the three-level SVPWM...
A new flexible digital platform based on the fixed-pointing DSP has been developed for power electronic systems integration, whose computational power can be easily expanded by floating-point units (FPU) which are configured by a FPGA. Some IP (intellectual property) cores for power electronic applications, coded in VHDL for modularity and portability, have been designed and validated in the digital...
