High frequency pulse width modulation implementation using FPGA and CPLD ICsHigh frequency pulse width modulation implementation using FPGA and CPLD ICs Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-172006enPulse width modulation (PWM) has been widely used in power converter control. Most high power level converters operate at switching frequencies up to 500 kHz, while operating frequencies in excess of 1 MHz at high power levels can be achieved using the planar transformer technology. The contribution of this paper is the development of a high-frequency PWM generator architecture for power converter control using FPGA and CPLD ICs. The resulting PWM frequency depends on the target FPGA or CPLD device speed grade and the duty cycle resolution requirements. The post-layout timing simulation results are presented, showing that PWM frequencies up to 3.985 MHz can be produced with a duty cycle resolution of 1.56%. Additionally, experimental results are also presented for low cost functional verification of the proposed architecture.http://creativecommons.org/licenses/by/4.0/Journal of Systems Architecture 526332-344 Koutroulis Eftychios Κουτρουλης Ευτυχιος Dollas Apostolos Δολλας Αποστολος Kalaitzakis Kostas Καλαϊτζακης Κωστας Elsevier Architecture, Software Computer software--Architecture Computer software--Design Computer software architecture software architecture architecture software computer software architecture computer software design
