is the DC power supply, 4 is the output side of the inverter circuit 2 and the transformer 3
A capacitor 4.5 is connected in series with the primary side of the acdle 4.5. Both the reactor 4 and the capacitor 5 are elements that constitute a filter. Waveform containing harmonic components output from inverter 2 (Figure 2) Beam accelerator 4
Since the wave is applied to the transformer as a positive arc wave as shown in FIG. 3, the loss in the transformer 3 due to harmonic components is reduced. Since a filter such as a capacitor 5 is also connected to the secondary side of the transformer 3 and the filter is supplied to the load, harmonic components output from the transformer 3 are also removed.
