Abstract

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, the circuits for the adjustments of modulation index and phase angle are synthesized onto a FPGA by means of hardware description language (VHDL). Since the VHDL statements, contrary to regular microprocessor programs, are inherently concurrent, highspeed response for determination of circuit output (switching state associated with the specified modulation index and phase angle) can be achieved. Experimental results are presented to verify the effectiveness and accuracy of the proposed configuration.
