“…All these results were obtained using XST (Xilinx Synthesis Tool) and Xilinx ISE v8.1. These results are comparable or even higher than those of the other state-of-the-art DPWMs based on delay lines [6][7][8][9][10][11][12].…”

“…In order to increase DPWMs resolution, delay-lines can be used. Given the interest of obtaining high resolution DPWMs, a lot of different architectures have been proposed in the last years [6][7][8][9][10][11], and even a classification of them has appeared [12]. Although all these architectures differ from each other, almost all of them make use of delay-lines.…”

Esta es la versión de autor de la comunicación de congreso publicada en: This is an author produced version of a paper published in: ABSTRACTPulse Width Modulation (PWM) is a very common technique used in different applications, from the control of motors, switching power converters (power supplies), audio amplifiers or illumination systems. In some of those applications, the pulse frequency has increased so much in the last years that the resolution obtained with classical (counter) techniques is not enough. This paper explains some methods used for increasing the resolution of PWMs and proposes a new method based on the resources available in almost every FPGA nowadays.

“…The core of the High-frequency segmented ring DPWM shown in Figure 6g is the modification of Figure 6d, with no external clock [32]. The architecture presented in [79], also resembles the DPWM architecture based on a ring oscillator, with a difference in the size of the structure.…”

Pulse width modulation (PWM) has been widely used in power converter control. This paper presents a review of architectures of the Digital Pulse Width Modulators (DPWM) targeting digital control of switching DC-DC converters. An attempt is made to review the reported architectures with emphasis on the ASIC and FPGA implementations in single phase and single-output DC-DC converters. Recent architectures using FPGA's advanced resources for achieving the resolution higher than classical methods have also been discussed. The merits and demerits of different architectures, and their relative comparative performance, are also presented. The Authors intention is to uncover the groundwork and the related references through this review for the benefit of readers and researchers targeting different DPWM architectures for the DC-DC converters.
