Capacitor reforming is realised by connecting a rectifier and a resistor
circuit to the converter DC link. The reforming circuit and component
values for different voltages are given below. See Figure 6-1 for the
reforming time.
WARNING! The converter supply must be disconnected while the
reforming circuit is connected.
