Symmetrical SVPWM pattern generator using field programmable gate array implementation

Pulse width modulation is used in power converters to modulate a reference signal into gating pulses, this conversion can be carried out using analog circuits or digital circuits, such as DSPs and microprocessors. A more efficient and faster solution is the use of field programmable gate arrays (FPGAs). This paper demonstrates how to generate a variable PWM waveform based on standard FPGA device, the proposed circuit is incorporated with a DSP to provide a simple and effective solution for high-performance PWM converters. Experimental results are given to prove the design methodologies and theoretical analysis.
