A novel partitioned hybrid PWM strategy to reduce the common‐mode voltage in three‐level neutral‐point‐clamped inverters

IET Power Electronics
To reduce the common‐mode voltage (CMV) generated during the operation of the three‐level neutral‐point‐clamped (3L‐NPC) inverters, this study proposes a partitioned hybrid pulse width modulation (PHPWM) strategy. In this strategy, the three‐level vector

Augmented Reality of Anatomical Structures of the Maxillomandibular Complex for Learning Dental Radiographic Techniques

Journal of Dental Education, EarlyView.
ABSTRACT Introduction Augmented reality (AR) enables interactive learning in real‐world environments. In dental radiography education, AR offers a promising tool to enhance students' clinical skills by allowing them to simulate and practice procedures before engaging with actual patients. Repeated practice in an AR environment can reinforce theoretical
