What is the meaning of current source?
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. An independent current source (or sink) delivers a constant current.
Is there any potential difference across current source?
A current source can certainly have a voltage across it. If the voltage across a current source is zero, then it is not delivering or absorbing any power. However, if the voltage across the source is not zero, then it is either sourcing or sinking power into the rest of the circuit.
What is the difference between ideal current source and practical current source?
Difference between an Ideal and Practical Current Source The ideal current source is supposed to have infinite internal resistance, . Practical Current Source has some internal resistance connected in parallel to Ideal Current Source. And some of the current flow through it and the amount of flow depends upon the load.
What is VSC and CSC?
Current-Source Converter (CSC) is a converter in which the DC-side current maintains the same po- larity; therefore, the direction of power flow is ad- justed by the DC-side voltage polarity. • Voltage-Source Converter (VSC), in contrast, keeps the same voltage polarity.
Can you have an ideal source in real world?
The ideal voltage source can 100% efficiently drop all of its voltage across a load. This is proven by ohm’s law. This would be an ideal voltage source. However, this does not and cannot exist in real life, because all voltage sources, such as batteries, will have some type internal resistance.
Why Statcom is used?
7.3 The static synchronous compensator (STATCOM) The STATCOM is a shunt-connected FACTS device that is used primarily for reactive power control. The STATCOM has two possible steady-state operating modes: inductive (lagging) and capacitive (leading). STATCOMs have been widely accepted to improve power system operation.
