New York: IEEE, p. 1432-1435, 2006.http://hdl.handle.net/11449/34231In this paper were investigated phase-shift control strategies applied to a four cells interleaved high input-power-factor pre-regulator boost rectifier, operating in critical conduction mode, using a non-dissipative commutation cells and frequency modulation. The digital control has been developed using a hardware description language (VHDL) and implemented using the XC2S200E-SpartanII-E/Xilinx FPGA, performing a true critical conduction operation mode for a generic number of interleaved cells. Experimental results are presented, in order to verify the feasibility and performance of the proposed digital control, through the use of a Xilinx FPGA device.1432-1435engTrabalho apresentado em evento10.1109/ISIE.2006.295682WOS:000244382902072Acesso aberto6427185658143370
