Essential Skills For Electricians - How To Correctly Select Dc Reactors And Ac Reactors

Hello everyone, my friends often ask me, what is the difference between DC reactor and AC reactor, how should I choose the reactor? Today, let's learn about the difference between DC reactor and AC Reactors, hoping to solve your doubts.

First, let's learn about DC reactor. DC reactor is a device used to regulate DC current. Its main function is to limit the AC component superimposed on the DC current to a certain specified value, keep the rectified current continuous, reduce the current ripple value, improve the input power factor, and suppress the harmonics generated by the converter.

AC reactor is a device used to regulate AC current. Its function is to limit the current shock caused by sudden changes in grid voltage and operational overvoltage, smooth the peak pulses contained in the power supply voltage, or smooth the voltage defects generated when the bridge rectifier circuit is commutated, effectively protect the power components inside the inverter and improve the power factor. It can not only prevent interference from the grid, but also reduce the pollution of the harmonic current generated by the rectifier unit to the grid.
