The inverter - really multiple-valued word. By this term it is designated several devices absolutely not similar at each other used in the most various industries of the equipment. You use some of inverters every day, at all without suspecting about it.
Historically, nameinverterthe logical element which is carrying out denial operation, or inversions became the first device which has received . In a different way it is called NOT element. If on its entrance to give logical unit, at the exit zero and vice versa will turn out. The person far from electronics, but familiar with electrical equipment, will remember the relay with normally closed contacts. Whether it is possible to consider it the inverter? Certainly. Modern technologies allow to do this device very tiny. So, for example, is located on tiny crystal of chip of their K561LN2 whole six. This logical element can be used and not for designated purpose. From two NOT elements if to add the resistor and the condenser to them, the generator of rectangular impulses turns out. It is easy to count that on one chip of K561LN2 can be constructed the whole three such generators. And it is the whole chord! And if to transfer the inverter to the linear mode, having given shift, the analog amplifier will turn out. But there are also other inverters. The second value of this term - tension converter. But not everyone, and only such at which both on entrance, and at the exit the stress is continuous (and, not very well, more it or is less entrance). Such converter consists of the generator and the rectifier. The first can be mechanical - the vibroconverter or the rotary converter, or electronic, executed on any suitable active element. The second can also be any two-output nonlinear element suitable on current, tension and frequency. Thanks to work at the increased frequency in modern inverters, despite big power, very small-sized transformers are used. So tiny that because of high concentration of power time they should be cooled with fans. Look around. Power supply units of the computer, TV, the charging device of the cell phone - all this inverters. And to have opportunity to eat alternating current, all of them are equipped on entrance with rectifiers with filters. And Panasonic - still only which uses such converters in microwave ovens that allows to do them by less heavy. But there will pass a little more time, on this decision the patent will expire, and all producers will begin to release such furnaces. And here invertor conditioners are called those not absolutely correctly. The fact is that the converter used in them intended for power supply of the engine by tension of the changing frequency has no at the output of the rectifier. So, such converter fits the definition of the inverter not absolutely. The same concerns also the devices developing from constant voltage of onboard network of the vehicle variable suitable for power supply of electrical household appliances.
