The ZVS-PWM commutation cell applied to the DC-AC converter
(1997-12-01)
This paper presents the analysis of a dc-ac converter using a zero-voltage-switching (ZVS) commutation cell. First, we show the cell applied to the buck converter. The stages of operation are presented along with the main ...
High-level multistep inverter optimization using a minimum number of power transistors
(2006)
Multilevel inverters with a large number of steps (more than 50 levels) can generate high quality voltage waveforms, good enough to be considered as suitable voltage template generators. Many levels or steps can follow a ...
phi meson mass and decay width in nuclear matter and nuclei
(Elsevier B.V., 2017-08-10)
The mass and decay width of the phi meson in cold nuclear matter are computed in an effective Lagrangian approach. The medium dependence of these properties are obtained by evaluating kaon-antikaon loop contributions to ...
Red blood cell distribution width to predict mortality in heart transplant recipients: a systematic review
(Page Press Publications, 2023)
Red blood cell distribution width (RDW) has been shown to have prognostic value in a number of different clinical settings, such as cardiovascular disease, including heart failure. However, its prognostic value in heart ...
Evaluation of transverse changes in the dental arches according to growth pattern: a longitudinal study
(2012-01-01)
Objective: To evaluate changes in intercanine (LICW and UICW) and intermolar (LIMW and UIMW) widths on the dental arches of subjects with normal occlusion and Angle Class I malocclusion during the transition to permanent ...

Scaling and width distributions of parity-conserving interfaces
(American Physical Society, 2013-09)
We present an alternative finite-size approach to a set of parity-conserving interfaces involving attachment, dissociation, and detachment of extended objects in 1+1 dimensions. With the aid of a nonlocal construct introduced ...
Mitigation of pulse-width-modulation distortion using a digital predistorter based on memory polynomials
(Elsevier Science, 2016-03)
This paper presents an adaptive digital predistorter (DPD) that significantly reduces the baseband distortion of digital pulse width modulation (PWM), typically used in switching (class-D) amplifiers. A generalized Hammerstein ...
