A Counter-Based DPWM Device with Resolution Extension
Applied Mechanics and Materials, 2011 Counter-based Digital PWM (DPWM), the simplest DPWM device, can be easily implemented only by a counter and a comparator; however, the resolution of the counter-based DPWM is directly proportional to its input reference clock, and thus the higher clock frequency is required, which means higher dynamic power consumption and noise interference may be ...

A Comprehensive Study on the Performance of DPWM in NPC Converter
2026 IEEE 9th International Electrical and Energy Conference (CIEEC)The Three-Level Neutral-Point-Clamped (3L-NPC) converter is widely used in high power, medium voltage applications, where the modulation strategy critically affects output performance. Discontinuous PWM (DPWM) is realized by clamping one phase for a period, yielding numerous possible methods. Beyond the commonly studied DPWM1 and DPWM3, the performance

Time-Domain Analysis of Sampling Effect in DPWM of DC–DC Converters
IEEE Transactions on Industrial Electronics, 2015This paper investigates time-domain analysis of sampling effect in digital pulsewidth modulation (DPWM) of dc–dc converters. The relation between the sampling delay, duty ratio, and multisampling factor (sampling to carrier frequency ratio) has been characterized.

DC-Link Capacitor-Current Ripple Reduction in DPWM-Based Back-to-Back Converters
IEEE Transactions on Industrial Electronics, 2018This paper proposes an improved offset selection method for discontinuous-pulse-width-modulation (DPWM)-based back-to-back converters to reduce dc-link current ripple. DPWM is introduced to power converters to diminish the stress on power transistors and prolong their lifespan.
