The first power Converter was used to obtain DC power from the electrical energy for electrification of industrial, commercial and station. At that time, was not called transformers, but were known as a rotary converters . They created the power in the same way as modern generators produce energy , with the exception of the system for supply of direct current instead of alternating current. Consisted of a DC generator or Dynamo and a set of slip rings evenly spaced around the windings of the rotor.
During the rotation of the Dynamo wytworzyłoby alternating current, which would be removed from the person dojeżdżającą, extracting DC. In fact, DC power, separately generated from the AC power using a synchronous Converter .
With proper management you can also set DC Converter so that it worked backward using the current DC for the production of electricity of the alternating current. Name inverter was invented, because at that time there was only the inverter rotary DC works “backward” or an inverted Converter . It is believed that David Prince coined the term inverter.
In 1925 Published a paper in the review of GE under the name “Inverter”, which contained nearly all basic elements of modern inverters. It was also the first known publication that uses the term inverter in the literature. In 1936, the inverter Prince has become common terminology in technical publications around the world.
How to operate the power Converter
The power Converter is required to convert direct current, such as that coming from the vehicle, into alternating current, which can be used for standard electronics. Early line converters the AC was Electromechanical . DC power, flowed from one end of the chain, to which was attached a magnet. When the current is contact with the magnet, it activates and will lead to the wire that was attached to the spring arm. It zmusiłoby wire for contact with the circuit by changing the current from one side to the other side of the circuit. At the same time, this will lead to removing power from solenoid.
When the magnet is fired, his spring shoulder back, providing a current flow once again from the original side chain. It aktywowałoby the magnet again, and repeat the process.
Modern line converters do basically the same thing, but instead use electromagnets and spring levers, are using semiconductors as switches . This eliminates the need for rotation of the shoulder in the back and in the front to change the current.
All currents create AC sine wave in some form. Home AC is a smooth, rounded sine wave, but there are many types of inverters generates a sine wave. It’s good for basic electronic devices such as coffee machines or mixers, but if we work with sensitive electronics that sends and receives transmissions, a square wave a sine wave can be problematic. Because of this, many modern inwerterów had a lot of filters, condensers and coils, which serve for cleaning of a sine wave, so it can be used in almost any electronic device.
How to choose an inverter
Choosing an inverter, the first step is to adapt the transducer to the voltage source. If you use the Converter with a battery car, you need 12-woltowego inverter, which is powered by a 12-volt car battery.
Once you have determined the correct voltage for the inverter, determining the power demand. To do this, you need to have an idea about electronics, you want to top-up using the inverter. Look at the labels on their devices that tells you the necessary power. The inverter should be able to produce at least this amount of power, more is better.
If we plan to power multiple devices at the same time, with inverter, it is necessary to add the required wattage for all devices. For example, if you have coffee that consumes 600 watts, and you plan to use both the toaster with 1000W power, you need a Converter with a capacity of not less than 1600 watts.
You should also consider the peak power. Some electronics use more energy when you run. This is known as peak power. For example, a blender can be regarded as the output of 600 watts, but has a peak power or the impact force of 800 watts. This means that when you start it consumes 800 watts, and then drops to 600 during operation. Most inverters also has the highest rated power, which is higher than the operating capacity because they are designed to handle this kind of load, but you should first check the peak power of both devices to make sure that they are compatible.
In the end you have to look at the result of the wave. As we mentioned earlier, the inverters generate, as a rule, a square sinusoidal wave, seem to have a lot of filters and coils, is introduced in order to smooth the waves. If you plan to use basic, non-audio and visual electronics, the output wave is not so important, but if you want to be able to work with laptop or charging your smartphone, this inverter with “great sinusoidą” should be taken into account. They can be quite expensive, so another option is inverter with modified sine wave . They will have a sufficient filtering so that they can be used with most electronics, but not perfect rounded wave.
