An electrical network can consist of sources and passive elements. Sources are circuit components which possess their own energy and are capable of transferring this energy to other circuit elements. There are two basic types of sources: voltage sources and current sources. These can be further classified as independent or dependent.

Voltage Source and Current Source

Show all documents Modelling and Simulation of Current Source Converter based Dynamic Voltage Restorer for Voltage Regulation cum Harmonics Mitigation Abstract— The modern electric power distribution system faces lots of power quality PQ problems such as short and long duration voltage variations, voltage imbalance, waveform distortions, impulsive and oscillatory transients and voltage flicker etc. The custom power devices CPD have been designed and developed with the aim of mitigating these problems. Through this paper, it has been attempted to develop a model of DVR system based on CSC topology capable of performing dual power quality enhancement tasks viz. Voltage source PWM converter is higher in efficiency, lower in cost, and smaller in physical size than the current - source PWM converter , particularly in terms of comparison between the dc capacitor and the dc inductor. Moreover the recent switching stress problems are less with Voltage source Converter Compared to Current source Converter.

voltage source to current source converter

A Source is a device which converts mechanical, chemical, thermal or some other form of energy into electrical energy. In other words, the source is an active network element meant for generating electrical energy. The various types of sources available in the electrical network are voltage source and current sources. A voltage source has a forcing function of emf whereas the current source has a forcing function of current. The current and voltage sources are further categorised as an ideal source or practical source. A voltage source is a two-terminal device whose voltage at any instant of time is constant and is independent of the current drawn from it. Such a voltage source is called an Ideal Voltage Source and have zero internal resistance.

A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it. A current source is the dual of a voltage source. The term current sink is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source driving a resistive load. There are two types. An independent current source or sink delivers a constant current.

The inverters are used to convert the power from dc to ac. The voltage source inverter VSI and current source inverter CSI are two types of inverters, the main difference between voltage source inverter and current source inverter is that the output voltage is constant in VSI and the input current is constant in CSI. The CSI is a constant current source which supplies ac to the input, and it is also called dc-link converter in which load current is constant. This article discusses the current source inverter. The current source inverter is also known as current fed inverter which converts the input dc into ac and its output can be three-phase or single phase. According to the definition of the current source, an ideal current source is the kind of source in which current is constant and it is independent of voltage.

If the car consumes more current than the alternator supplies, the system voltage is supported by the battery, but lower than the "pure battery voltage" again due to the internal resistance of the battery.

Он был известен среди сотрудников, он пользовался репутацией патриота и идеалиста… честного человека в мире, сотканном из лжи. За годы, прошедшие после появления в АНБ Сьюзан, Стратмор поднялся с поста начальника Отдела развития криптографии до второй по важности позиции во всем агентстве. Теперь только один человек в АНБ был по должности выше коммандера Стратмора - директор Лиланд Фонтейн, мифический правитель Дворца головоломок, которого никто никогда не видел, лишь изредка слышал, но перед которым все дрожали от страха. Он редко встречался со Стратмором с глазу на глаз, но когда такое случалось, это можно было сравнить с битвой титанов. Фонтейн был гигантом из гигантов, но Стратмора это как будто не касалось.

Это явно не было составной частью плана. - У них там прямо-таки дискотека! - пролопотал Бринкерхофф. Фонтейн смотрел в окно, пытаясь понять, что происходит. За несколько лет работы ТРАНСТЕКСТА ничего подобного не случалось. Перегрелся, подумал .
