I'm wondering as to how a system like this:

this

acts, when their thyristors are controlled in various ways.

The converters are simple enough, but I'm wondering how the graph made around the voltage going over the resistor \$R\$ would look like when the thyristors are set top \$0^\circ\$ and \$90^\circ\$ respectively.

  • \$\begingroup\$ Thanks, that was a massive help. How does the frequency of the current project to the frequency of the sine-waves; is it directly relatable? (50 hz would mean that one complete sine-wave or two converted "mounds" are 20 milliseconds?) \$\endgroup\$ – Grak Apr 19 '17 at 10:52

There are several alternative topologies for controlled rectifier bridges. The one in your diagram is called a half-controlled bridge. The associated waveform is shown below.

Here is the description of operation:
