Pulse-width modulation of power electronic DC-AC converter
, 2021 The pulse-width modulation (PWM) technique is applied in the inverter (DC-AC converter) to output an AC waveform with variable voltage and variable frequency for use in mostly variable speed motor drives. This chapter provides an overview of the PWM techniques based on the most basic and classical sinusoidal carrier-based scheme to modern space vector ...

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction
Advanced Healthcare Materials, EarlyView.Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...
