IEEE transactions on industrial electronics (1982. Print), 2023
This article proposes an ultrahigh step-up dc–dc converter composed of two boosting stages, a coupled inductor, and switched capacitors. Advance features of the converter consist of its high voltage gain, low voltage stress on its switches, continuity of

Field Measurements Of Touch And Step Voltages
IEEE Transactions on Power Apparatus and Systems, 1984This paper presents the study of a measurement technique for touch and step voltages and the results of measurements obtained inside and outside substations. Details of a low-voltage and a highvoltage method of current injection are given. Setups for measuring the shock touch voltage and shock step voltage are characterized, in which the effect of foot

An improved method of voltage stepping
International Journal of Mass Spectrometry and Ion Physics, 1969Abstract A unit providing sequential stepping over up to eleven mass positions is described. Operation may be in a straight sequence or in one with the reference mass monitored alternately with measurements at the other masses. Performance tests show that the latter mode of operation permits higher precision by virtue of the more frequent monitoring ...

Influence of a Step-Voltage Regulator on Synchronous DG Anti-Islanding Protection
IEEE Latin America Transactions, 2019The performance of anti-islanding frequency and voltage protections is strongly affected by the power imbalance between the islanded loads and distributed generators, which is altered by changes of load demand.

Novel voltage control of multiple step voltage regulators in a distribution system
ISGT 2014, 2014This paper presents a novel method for determining the control parameters and a voltage control method for multiple step voltage regulators (SVRs) in a single feeder. The main purpose of the proposed method is to reduce the amount of voltage violation and the tap operation times and to extend the voltage margin from the upper and lower voltage limits ...
