Principle of Inverter of Frequency converter(1)

Installation of appropriate reactor.

The input power factor of the converter depends on the AC-DC conversion circuit system inside the device. The shunt power factor can be used to correct the DC reactor, and the power side of the AC reactor can be connected in series. The THDV of the incoming current is reduced by about 30 to 50, which is about half of the harmonic current without the reactor.
