Line-to-Neutral Coupling Style
In the following section the simple circuits shown in figures 4.4 and 4.5 are expanded
to make them practical in real applications. The following discussion applies to both
line-to-neutral coupling and line-to-earth coupling, as the coupling circuit topology
for each is the same. However, in addition to the different mains connections, the
required component values differ for line-to-neutral coupling and line-to-earth
coupling. At the end of this chapter, recommended coupling circuit schematics and
component specifications are provided for both line-to-neutral coupling and line-to-
earth coupling.
