Abstract:
High demand on voltage regulator (VR) currently requires VR manufacturers to improve their time-to-market, particularly for new product development. To fulfill the output stability requirement, VR manufacturers characterize the VR in terms of the equivalent series resistance (ESR) of the output capacitor because the ESR variation affects the VR output stability. The VR characterization outcome suggests a stable range of ESR, which is indicated in the ESR tunnel graph in the VR datasheet. However, current practice in industry manually characterizes VR, thereby increasing the manufacturing time

Abstract:
This paper proposes a comparison between two methods of voltage regulation of over sending-end voltage in case of the load located near a substation. The first method is using tab change of power transformer and the other is the installation of voltage regulator in a factory. In the process, voltage level is completely measured before and after the installation of techniques, and is slightly decreased until it approaches to the lowest demand of loads, which can normally operate in the plant. The sequent test results show that the first method, sending-end voltage control via voltage regulator,

Abstract:
This study aimed to propose individual phase voltage regulation strategies using the sparrow search algorithm (SSA) in the IEEE 8500-node large-scale unbalanced distribution network with high photovoltaic (PV) penetration. The proposed approach is capable of individual phase regulation, which coordinates the on-load tap changer (OLTC), voltage regulator (VR), switched capacitor bank (SCB), and volt–var setting controlled by a smart inverter to improve voltage variation and unbalance. Consequently, the change time of VRs, the switched times of SCBs, and the individual phase voltage magnitude an

Abstract:
This work proposes multi-objective two-stage distribution optimal power flow (D-OPF) to coordinate the use of smart inverters (SIs) and existing voltage control legacy devices. The first stage of multi-objective D-OPF aims to solve a mixed-integer nonlinear programming (MINLP) formulation that minimizes both voltage variation and active power loss, with SI modes, SI settings, voltage regulator (VR) taps, and capacitor bank (CB) status as control variables. The Pareto Optimal Solutions obtained from the first-stage MINLP are used to determine the optimal active–reactive power dispatch from the

Abstract:
Appropriate design of Multi-Port Converter (MPC) topology helps to overcome the difficulties of combining numerous renewable energy sources (RES). In this article, a comprehensive analysis of these MPCs in terms of their topologies, operating principles, various dependability, and overall efficacy is offered. There are two main types of MPCs which are non-isolated and isolated MPCs being coupled in parallel and series configurations to function as multi-input converters. These MPCs can flow the load power in one or both directions for the RES or BESS (battery energy storage system) application

Abstract:
A novel low line regulation voltage reference (VR) without an amplifier is presented in this paper. The design is achieved by subtracting two voltages which have the same temperature curves. All circuits use only one Bipolar Junction Transistor (BJT) to decrease the area greatly. Designed with the SMIC 0.18[Formula: see text][Formula: see text]m CMOS process, the simulation results show that the output voltage is 0.902[Formula: see text]V at TT process corner when the power supply is larger than 1.7[Formula: see text]V.

Abstract:
In recent years, the penetration of renewable energy sources (RES) in microgrids and distribution system feeders has increased manifold. Moreover, the advancement of power electronics-based devices in the distribution system has significantly increased the number of sensitive loads. Variations in the voltage under intermittent RES create functional problems with sensitive loads, necessitating voltage regulators (VR) installation. In this paper, two custom power devices: dynamic voltage restorer (DVR) and static synchronous compensator (STATCOM), used for voltage regulation in a microgrid, are

Abstract:
Determination of the placement and rating of transformers and feeders are the main objective of the basic distribution network planning. The bus voltage and the feeder current are two constraints which should be maintained within their standard range. The distribution network planning is hardened when the planning area is located far from the sources of power generation and the infrastructure. This is mainly as a consequence of the voltage drop, line loss and system reliability. Long distance to supply loads causes a significant amount of voltage drop across the distribution lines.

Abstract This paper presents a novel approach in analyzing power distribution network (PDN) from a failure analysis perspective. PDNs, although technically should only have DC component, due to the nature of digital systems it powers and the way current is drawn in time and frequency domains, it is essential to look at AC component as well. AC component: impedance plays a huge role in PCB power rails and the different components (active and passive) that connect to it. Different components (i.e., voltage regulators (VR), bulk capacitors, ceramic capacitors, etc.) influence different frequency

Abstract:
With increasingly high powers on processors, memories, and chipsets, the voltage regulators (VR) become heavily loaded and a heatsink is often required to prevent overheating the surrounding components on the board. For VR heatsink designs, thermal interface silicone gap filler pads are often used and there is an increasing need to improve VR thermal solutions by reducing thermal resistance of the TIM. A series of TIM2 thickness and performance measurements based on thermal testing was performed in order to understand gap filler characteristics, optimize TIM performance, and utilize best reten
