Inverters are not rare device. Under other names, they appear in numerous applications. Inverters, of course, you can call and vibration transducers and generators of feedback, and relaxation oscillators. Do they make the DC voltage to AC? In fact, using the names “inverter” and “generator” is somewhat arbitrary. The inverter can be the generator and the generator can be used as an inverter. Usually preferred to use the term “inverter”, when the operating frequency was less than 100 kHz, and the operation performed by them ensures variable voltage circuit or some other equipment. Modern inverters have no restrictions on the frequency.
