SPWM GENERATOR BASED ON FPGA FOR HIGH SWITCHING FREQUENCY DC/AC INVERTERS

dominated over their counterparts based on analog circuits. Here an FPGA based SPWM generator is implemented, which is capable to support the high switching frequencies more than 1 MHZ, thus it is capable to support the high switching frequency requirements of modern single-phase dc/ac power converters. This design occupies a small fraction of a medium sized FPGA and, thus can be integrate in larger designs. In addition to that, it has a flexible architecture that can be implemented to a variety of single-phase dc/ac inverter applications. This experimental results confirm that compared to the past-proposed microcontrollers and DSPs generation unit designs, the SPWM generator exhibits much faster frequency, lower power consumption, and higher accuracy of generating the desired SPWM waveform
