The Effect Of Reactor On Frequency Converter



The effect of the reactor on the inverter is used to limit the voltage mutation and the current impact caused by the operating overvoltage. Smooth power supply voltage included in the spike pulse, or smooth bridge rectifier circuit commutation when the voltage defects, effectively protect the inverter and improve the power factor, it can not only prevent interference from the network, It can also reduce the harmonic currents generated by the rectifier unit to the network pollution. The details are as follows:

First, the output reactor: The main role is to compensate the long-term distribution of capacitance, and can suppress output harmonic current, improve the output of high-frequency impedance, to protect the inverter, to reduce the role of equipment noise. When the capacitor is compensated, the harmonic voltage and the harmonic current are often impacted, which causes the capacitor to be damaged and the power factor is reduced.

Second, the role of DC reactors: DC reactor connected to the inverter system of DC Rectifier link and the inverter link between, the main purpose is to limit the AC component superimposed on the DC current to a specified value, keep the rectifier current continuous, reduce the current pulse value, make the inverter run more stable and improve the power factor of the inverter.
