High boost DC/DC voltage conversion is always indispensable in a power electronic interface of certain battery-powered electrical equipment. However, a conventional boost converter works for a wide duty cycle for such high voltage gain, which increases power consumption and has low reliability problems. In order to solve this issue, a new battery-powered combined boost converter with an interle...

A DC–DC switching converter chip is proposed to generate both positive and negative voltages for active-matrix LCD (AMLCD) bias. An inductive boost converter and two inverting charge pumps are integrated in a proposed chip by using a 0.5 mm 5 V, 3.5 mm 30 V CMOS process. A conventional scheme used to bias AMLCD employs a switching-boost converter with several off-chip components to generate the...

PURPOSE To report the results of a correlation analysis of skin dose assessed by in vivo dosimetry and the incidence of acute toxicity. This is a phase 2 trial evaluating the feasibility of intraoperative radiotherapy (IORT) as a boost for breast cancer patients. MATERIALS AND METHODS Eligible patients were treated with IORT of 20 Gy followed by whole breast irradiation (WBI) of 46 Gy. A tota...

A compact High Voltage (HV) module for generating 100V DC output has been developed for biasing of PIN photodiode detector used in dosimetry applications. Two different approaches have been used in designing the HV circuit. In the first case, the circuit employs a low noise, constant frequency pulse width modulating (PWM) boost converter with an inductor operating in

Exact time-dependent solutions of nonrelativistic noncommutative Chern Simons gauge theory are presented in closed analytic form. They are different from (indeed orthogonal to) those discussed recently by Hadasz, Lindström, Roček and von Unge. Unlike theirs, our solutions can move with an arbitrary constant velocity, and can be obtained from the previously known static solutions by the recently...

This paper presents an efficient maximum power point tracking (MPPT) controller for a standalone photovoltaic (PV) generation system. To achieve an efficient MPPT controller, a new boost converter design and an improved MPPT algorithm are incorporated. In the proposed boost converter design, a passive regenerative snubber circuit is included to absorb the energy of stray inductance so as to red...

In this paper, a MSEBC (modified-SEPIC embedded-boost converter) is proposed, which can deal with either utility power or PV (photovoltaic) power to serve as HB-LED (High-Brightness Light-EmittingDiode) driver and battery charger. While connected to utility, the proposed converter can perform PFC (power factor corrector) for universal line input. Once power failure occurs, it can draw energy fr...
