This paper presents a multilevel converter with regeneration capability. The converter uses several power cells connected in series, each working with reduced voltage and with an active front end at the line side. This paper presents the following: 1) the control method of each cell; 2) the use of phase-shifting techniques to reduce the current and voltage distortion; and 3) criteria to select ...
In this paper, a 0.18-V input three-stage charge pump circuit applying forward body bias is proposed for energy harvesting applications. In the developed charge pump, all the MOSFETs are forward body biased by using the inter-stage/output voltages. By applying the proposed charge pump as the startup in the boost converter, the kick-up input voltage of the boost converter is reduced to 0.18 V. T...
Domestic service robots are currently powered by the mains electricity. The growing multiplication of such devices negatively impacts our environment. In this study, we show the feasibility of harvesting energy from natural light in an indoor environment. The design of the harvester is carefully carried out using an experimental characterisation of several solar panels, while the boost converte...
BACKGROUND Outcome data in young women with ductal carcinoma in situ (DCIS) are rare. The benefits of boost radiotherapy in this group are also unknown. We aimed to assess the effect of boost radiotherapy in young patients with DCIS. METHODS We included 373 women from 18 institutions who met the following inclusion criteria: having tumour status Tis and nodal status (N)0, age 45 years or youn...
This paper describes the development of discourse cohesion in bilingual children, through an analysis of narrative discourses produced by hearing children of deaf parents (HCDP) in both British Sign Language (BSL) and spoken English. Reference mechanisms in both languages are described in the context of recent work on narrative and discourse organization development in spoken and sign language....
In this letter, chaos in a current-mode controlled boost converter is studied. Firstly, the existence of chaos is proven theoretically in this system. The proof consists of showing that the dynamics of the system is semiconjugate to that of a one-sided shift map, which implies positive entropy of the system and hence chaotic behavior. The essential tool is the horseshoe hypotheses proposed by K...
1 This work is supported by Philips Research, Briarcliff Manor, NY, through Colorado Power Electronics Center Abstract – Single-switch step-up/step-down converters, such as the buck-boost, SEPIC and Cuk, have relatively high voltage and current stresses on components compared to the buck or the boost converter. A buck-boost converter with two independently controlled switches can work as a boos...
Purpose: Combination of Prostate Seed Implant (PSI) with External Beam Radiation Therapy (EBRT) remains as an attractive option for patients with intermediate or high-risk prostate cancer. One of the most widely used approaches is to use external beam radiation therapy (EBRT) to deliver boost doses after permanent prostate seed implant (PSI). In this study, the feasibility of using Intensity Mo...
We study ionization and transport processes in partially ionized multicomponent plasmas. The plasma composition is calculated via a system of coupled mass action laws. electronic properties are determined by the electron-ion electron-neutral cross sections. influence electron-electron scattering considered correction factor to contribution. Based on this data, electrical thermal conductivity as...
