INVESTOR The circuit is capable of converting direct current , ie the flow of electrons generated by a battery (better known as "stack") in AC, which is what makes it possible for our operate appliances and businesses like CFE or Luz y Fuerza del Centro provided to our homes.
However, to begin with that letter in the above example we refer to the conversion or exchange of a higher voltage to a desired voltage, therefore, the case will there be a connection between our example and the definition given above? The answer to this question is yes, because to start voltage and current are concepts that ARE NOT BARE each other.
VOLTAGE AND CURRENT. We first clarify the terms of voltage and current, to know what really changes the investor. First, the electrical voltage is force that has an electric generator, ie by subtracting the electric charge of the poles Positive and negative generator. Let's put it this way, suppose we have 2 containers full of water, one is placed above the other. The force with which a drop of water from one container to another depends on the rest of the heights between two containers. The greater the height, the greater the force to occur. This force is produced by a flow of electrons known as power.
Now electric current is the movement of charges or electrons through a closed path. These electrons are generated by a source of electromotive force. This source of electromotive force (such as a battery, generator or other device) is able to put in motion negative electric charges (which are the electrons ) continuously negative terminal of the source to the positive of it. Finally, a closed path is merely a way which allows these electrons to flow from a negative pole to the other. If along this path is a device or mechanism that causes resistance (ie to prevent the flow of electrons), this device is called load or resistance , which uses these electrons to function Such is the case of bulbs, televisions, motors.
Finally, the AC is a type current in a certain time in one direction and then in another sense, hence I called AC , because in specific periods of time meaning that it takes to travel a path changes. This type of current that comes into our homes and operate televisions, washing machines, computers and other appliances.
What is the relationship between these two concepts? Well, in the world there materials that hinder plus the passage of electric current others (ie, its value is greater than supply). If resistance increases, current decreases and vice versa, as long as they apply the same strength or electrical voltage is, this voltage is kept constant . Now, if the voltage increases or decreases, is current flowing through the circuit who will increase or decrease in proportion to the voltage, if the value of connected to the circuit resistance remains constant. We therefore conclude that the voltage is generated by the current and vice versa as long as they have the same resistance. This is known as Ohm's law .
Figure we can see the battery that is displayed or "stack" electrons set in motion a path running through the negative terminal of the "stack" the pole very positive. The same electron flow generates a force that varies with the movement of electrons as long as they keep the same charge which is denoted by the letter R. E, symbolizes the power or voltage and I represents the flow of electrons also known as current.
inverter operation. Having clarified what is current and voltage, we will explain how an investor. The INVESTOR whose function is to change the voltage or "force" caused by a direct current (or flow of electrons) of a battery output voltage or "force" obtained the inverter output which is now AC , which now can be manipulated to the user or designer.
The figure shows the representation of an inverter where V in terms of the voltage or "force" input which is generated by a battery and V out the output voltage or "force" which is obtained by the investor. The "triangle" seen in the figure is the symbol that represents the investor.
Now, how does this compound an investor? Digital electronics brand that consists of sections INVESTOR known as Section OSC, amplifier section and Transform section, where they are involved an oscillator, a transistor and a transformer, respectively.
Its operation is simple as that section oscillator, oscillator responsible for generating electrical pulses to the alternating current to provide the investor is equal to the alternating current provided by the service company electric. Then the transistor in the amplifier section causes an interruption in the incoming stream, obtaining results in the generation of a square wave, whose job is to "feed" the transformer on the elevated section, generating a continuous signal (or sinusoidal) it gives us the voltage output needed for our equipment continues to operate.
APPLICATIONS. The UPS or translated into Castilian UPS (uninterruptible power supply) are examples of practical application is given to an investor.
Physically a UPS is like the one shown in the picture above.
sources used to supply power to a computer at a time of lack of public provision. In other words, what do these sources is that in the event of a "blackout" to provide electricity to the appliance connected to the continued functioning. Batteries usually contains a UPS are from 6 volts and up. Another role of a UPS is to regulate the alternating current that feeds our apparatus, since due to voltage variations (which is synonymous with power and voltage), our engine can even burn.
The block diagram We can see the above sections that make up this SAI. In Figure 2 we can see that the oscillator section is where the battery itself that is to the bottom of the drawing. This section will be responsible for generating electrical pulses that empty into the inverter, which is marked with the number DD744.
raised section, is where is located the transformer, which is fed by the amplifier section. This results to generate 230 V AC.
Other applications are given to investors, in addition to UPS, they are like ACTUATORS MOTORS AC, whose mission is to generate the movement of the elements that make up the engines and are used very often in the field of robotics. Another application of the investors is on photovoltaic generation, where these circuits are responsible for the conversion DC power generated by photovoltaic panels into alternating current and thus can be injected into a power grid or used in electrical isolation. For this and for many applications that investors are investing the world.
