Dipartimento di Ingegneria Elettrica Industriale, Politecnico di Torino, C.so Duca degli Abruzzi 24, 10129 Torino, Italy View references (8) Abstract In the field of PWM power converters, the newest low-cost FPGAs are investigated as alternative digital control devices. The paper would show how FPGAs allow for unprecedented performances. A comparative overview of DSP and FPGA is carried-out on loop dynamics vs PWM ripple and noise immunity. The FPGA-based top-performance solution is defined and applied, based on oversampling and parallel processing techniques. An FPGA-based development PCB has been designed and realized accordingly suited to control three different inverters and two H-bridge converters. The new control concepts are applied to coupled DC/DC H-bridge boost converters as the strongest test bench due to multiple PWM properties. Experimental performances are very satisfactory.
