This paper presents a complete design scheme of the Space Vector PWM (SVPWM) integrated circuit, including dynamic optimization of switch frequency, dynamic modulation with variation DC-link, and linear- and over-modulation strategies. The entire design is implemented and verified on a single Altera FPGA. A new Top-Down design method on FPGA is proposed in this paper. Generally speaking of the design...
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,...
