The function of the inverter is to convert the sine wave voltage of fixed voltage and frequency value from the grid into a rectangular wave voltage with fixed amplitude, variable frequency and variable pulse density, and then supply DBD type ozone generating device.
Frequency converter architecture is divided into: three-phase input single-phase output of the inverter (including NLOPS-11kW, NLOPS-22kW, NLOPS-37kW, NLOPS-55kW, NLOPS-90kW) basic architecture as shown in Figure 1-3a; The basic architecture of the output inverter (including NLOPS-110kW, NLOPS-225kW) is shown in Figure 1-3b.
