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 low-cost and effective approach to generate harmonic elimination PWM (HEPWM) waveforms for three-phase voltage-sourced inverters (VSIs). In the developed approach, the off-line computations of switching patterns based on harmonic elimination strategy are stored in EPROM, thereby allowing a microprocessor-free design. With the proposed configuration, the circuits for the adjustments...
