The main difference between the reactor, transformer, inverter, and their respective principles of operation. I don't want to baidu paste ah, a little more vulgar, thank you!

Reactor: can resist the change of current, and make the change slower. Remember the high school physics class learned capacitance, inductance it, reactor is inductance. It is actually a coil, when the current through the coil changes, it will first cause changes in the coil magnetic field. The effect is actually to slow down the trend of the current. For example, when there is a short circuit, the current in the circuit suddenly becomes large, the reactor will resist the current change in a short period of time, play a protective role.

Transformer: as the name implies is used to change the voltage. In the case of an AC transformer, for example, two sets of coils are wound around a toroidal magnetic conductor. The input coils are energized to produce a magnetic field, and the output coils produce induced electricity. Since the magnetic flux in the two coils is the same, but the number of coils is different the output voltage has a constant ratio to the input voltage. In this way we can get any desired voltage.

Inverter: change the frequency of the alternating current. Lighting circuits, for example, voltage 220V frequency 50-60Hz. in the use of three-phase asynchronous AC motor when we need to control the motor speed to control the frequency of the input voltage. The principle of operation is to change the alternating current into direct current, and then through the switching circuit into the required frequency of pulse voltage.

This is a good way to remember: the reactor is to control the current, the transformer is to control the voltage, the frequency converter is to control the frequency of the alternating current.

Simply put, there are these, and do not understand and then ask it
