Abstract:

In this paper, a low-voltage low-dropout analog regulator (ALDO) based on a native n-channel MOS transistor is proposed. Application of the native transistor with the threshold voltage close to zero allows elimination of the charge pump in low-voltage regulators using the pass element in a common drain configuration. Such a native pass transistor configuration allows simplification of regulator design and improved performance, with supply voltages below 1 V, compared to commonly used regulators with p-channel MOS transistors. In the presented design of ALDO regulator in 180 nm CMOS X-FAB techn

The present paper is dedicated to an unusual analysis of an autotransformer discrete alternating voltage regulator presented as a two-port with a load. The main purpose of the study is to determine the different sets of parameters (matrices) of this two-port – ABCD, B–, H-, G-, Z-, Y-parameters and the characteristic parameters. A Matlab simulation model of the autotransformer discrete alternating voltage regulator with four commutators, realized by thyristor switches, corresponding to different supply voltages, is used for the analysis.

Abstract Series linear voltage regulators are integrated circuits commonly used to make adjustable voltage sources. When used with potentiometers, these regulators are able to give adjustable voltage at the output. Memristor is a new nonlinear circuit element which came out in the last decade. It is able to provide electronically adjustable resistance. If a memristor is fed with a voltage over the threshold and it is not under saturation, its resistance also called memristance is dependent on the integration of its current, also called memristor charge.

Abstract:

Although there currently exists a wide range of voltage regulators that are commercially available, the search for devices with a simpler physical design remains the focus of research studies. Following this line, an electromagnetic voltage regulator (EVR) arrangement has been proposed. The EVR is constituted of an autotransformer that supplies, via discrete taps, a series transformer that injects voltage for regulating the feeder voltage. Even though its operating principle is shown as being similar to that of other devices on the market, the physical arrangement and operating strategy of EVR

A method of on-line monitoring of the low-dropout voltage regulator's operation in a radiation environment is developed in this paper.

Penetration of equipment such as photovoltaic power generations (PV), heat pump water heaters (HP), and electric vehicles (EV) introduces voltage unbalance issues in distribution systems. Controlling PV and energy storage system (ESS) outputs or coordinated EV charging are investigated for voltage unbalance compensation. However, some issues exist, such as dependency on installed capacity and fairness among consumers. Therefore, the ideal way to mitigate unbalanced voltages is to use grid-side equipment mainly.

Abstract:

This paper proposes a new optimized control of photovoltaic two stages conversion cascade composed by Three Levels Boost (TLB) and Three Levels Neutral Point Clamped (TLNPC) inverter. In order to extract the maximum power from photovoltaic generator and get a balanced DC bus voltage, the duty cycles of the two TLB switches are determinate from a Fuzzy Logic Controller (FLC) for the first switch and by adding to the first duty cycle an additional duty cycle obtained by integration of the error between the two capacitors voltages of DC bus. Balancing the bus voltages by the TLB using a single re

Abstract:

Induction motors are firmly entrenched in modern industry due to the unpretentiousness of operating conditions and relative low cost. Induction motors have a number of problems, one of which is high starting currents, which exceeds the nominal by 6-8 times and leads to false alarms of the automatic protection and to reduction of induction motor life. This problem is solved by installing soft-start devices in the electric circuit. The principle of operation of such devices is based on regulating the voltage supplied to the stator windings of the induction motor from 0 to the nominal value of th

Abstract:

In this paper, a power regulated circuit (PRC) is proposed for system-on-a-chip (SoC) applications. The proposed PRC is composed of a limiter, a bandgap reference (BGR), three low-dropout regulators (LDOs), and a bias generator. A high output voltage of an active rectifier is given to the limiter, which limits it to a desired supply voltage for circuits in PRC. The curvature-compensated BGR robust to process, voltage and temperature (PVT) variations are designed to provide a stable reference voltage for three LDOs. The three LDOs are implemented to generate regulated output dc voltages. The pr

Abstract:

In today’s modern systems on chip (SOCs), a crucial power management circuit is the low-dropout (LDO) regulator. Of course, the need for supply voltage regulation, goes back many years in the past since the circuits have been designed. Today, LDO based voltage regulators are frequently used in a number of mixed-signal systems to produce local supply voltages that feed different building blocks. LDOs try to isolate the noise of the circuit and noise from the global supply and try to reduce their effect on device performance. For the state of desired achievement, each LDO’s architecture is circu

An integrated ramp generator is presented in this paper. For traditional implementations, the amplitude clamp is realized with zener diode to limit the output voltage to ±VZ, while the zener diode is not available for standard CMOS process. The transmission gate is utilized to make the output voltage in the determined range. The reference voltage is provided by a bandgap voltage reference with temperature compensation, which guarantees the temperature stabilization of the frequency of the ramp generator. The ramp generator was fabricated in a commercial CMOS process. The frequency of 44kHz is

Abstract:

The voltage in distribution systems is controlled by the under-load tap changer of the substation and the pole transformer of the primary feeders. Recently, as one of the main countermeasures, a step voltage regulator is being introduced to solve voltage problems such as overvoltage phenomena in a distribution feeder interconnected with a renewable energy source and under voltage in a long-distance feeder. However, the tap of the step voltage regulator may be frequently operated due to its interdependent relationship with the under-load tap changer in the distribution system. Furthermore, give

Since the regulation of voltage supply is one of the most critical requirement of the electronic system design, the monolithic voltage regulator has become one of the most important building block of both analog and digital systems. This importance has been recently increased with the emergent low voltage technologies, encouraging industrials and researchers to work on new regulator structures. The voltage regulator presented here, has been first calculated and simulated through PSpice. The paper deals with the conception of a series voltage regulator integrated in 0.6Âµm CMOS technology.

Abstract:

The main function of the on-load tap changing (OLTC) regulators consists of maintaining a constant voltage in order to feed critical loads despite the load changes or voltage changes in the ac mains. The traditional regulators are still used nowadays, but they present several disadvantages, like a slow response, which reaches from 100 ms to several seconds. These drawbacks can be overcome if the OLTC regulators would have shorter response time, commuting several times every cycle of the mains. There are two basic topologies for fast OLTC regulators. The first one consists of several taps and u
