Boost power factor correction circuits
Conference Record Southcon, 1994In this paper, we present two modified boost converter topologies to be used as power factor correction circuits. Zero-voltage switching and proper transformer-core resetting are achieved utilizing the parasitic capacitance of the switch and the magnetization inductance of the transformer. Steady state analysis for the two circuits is given.

“Wow-Factors” for Boosting Business
2016WOW, that’s great, what that company is doing. This comment is human factor in business context in its purest form. Wow-factor is something that won’t only separate the company from others, but separates it superiorly. Wow-factor is the factor that already exists in companies’ business and affects to people in many cases.

IET Power Electronics, 2019
In this study, a new switching pattern for switched Z-source inverters (ZSIs) is proposed. By this technique, the switched ZSIs can generate general boost factor with different functions.

A boost unity power factor pre-compensator
2008 IEEE Power Electronics Specialists Conference, 2008In this contribution, a passivity-based output feedback controller is developed for the unity-power-factor pre-compensation of a boost-type AC/DC power converter. In such applications, aside from load voltage tracking to a pre-specifled initial and final constant level, a vital additional control objective consists in keeping the input power factor ...

Oxygen sensor boosts growth factor signaling
Nature Medicine, 2009Activation of hypoxia-inducible factor, a molecule central to oxygen sensing, can promote the survival and growth of tumor cells. New experiments dissect a pathway behind this effect—upregulation of the epidermal growth factor receptor ( pages 319–324 ).

Resources policy, 2023
The energy consumption structure is now shifting from using fossil fuels to using renewable energy. Thus it is crucial to research if decreasing energy use can genuinely boost green total factor productivity (GTFP) and how to reconcile the link between ...

Soft-switched high-power-factor boost converter
2004 10th International Workshop on Computational Electronics (IEEE Cat. No.04EX915), 2005A novel implementation of the high-power-factor (HPF) boost converter with active snubber is described. The snubber circuit reduces the reverse-recovery-related losses of the rectifier and also provides zero-voltage switching (ZVS) for the boost switch and zero-current switching (ZCS) for the auxiliary switch.

IEEE transactions on industrial electronics (1982. Print), 2019
In this paper, a digital-based pulse train (PT) control technique for a boost power factor correction (PFC) converter operating in a discontinuous conduction mode (DCM) is presented, which can achieve nearly unity power factor (PF) over a universal input

Resonant-boost-input three-phase power factor corrector
IEEE Transactions on Power Electronics, 1999The paper presents a new three phase PFC circuit in which the power switches work in ZVS soft switching condition. The THD in the input current has been reduced about 4.5% and the output DC voltage is very close to the peak line voltage (for 204 V line, RMS three phase system, the output DC voltage is 300 V).
