+C BENCHMARK DC-32
+C Artificial 6-pulse dc power supply that illustrates the simulation of
+C diodes. It was concocted in July of 1977 to instruct Hughes Aircraft in
+C Fullerton, California (Emory Johnson, Gene Perusse, and assoc.). Use of
+C MEMSAV = 1 dumps tables for later restarting and modification (see DC-49).
+C It is assumed that STARTUP has KTRPL4 < 0 and L4BYTE = 1 so that a
+C C-like ".PL4" file having name DC32.PL4 will be created (used by DC-49).

+C Three 2-winding saturable transformers having unity turns ratios are
+C delta-connected on the source side, and grounded-Y on the rectifier
+C side. The magnetizing branch is both nonlinear and lossy:

+C Small impedance branches are used (prior to "M34." generalized switch
+C logic) to isolate switches from each other at "POLEA". R = 5 ohms.
+C Although in theory such isolation is no longer required, do not try
+C to remove these 9 resistors, since they provide necessary damping.
+C Note that these resistors are not of negligible value:
+ CATH1 POLEA 5.0
+ CATH2 POLEA CATH1 POLEA
+ CATH3 POLEA CATH1 POLEA
+C More small impedances used for switch isolation at node "POLEB", and
+C also at the transformer secondary. Half the value of "POLEA" is used,
+C for balance:

+ CATH5 SECA CATH4 SECC

+C 2-conductor distributed line connects "POLE" with "LOAD". Inductance
+C parameters are 5.8 and 1.6 millihenries for the ground and sky modes,
+C respectively. Length is five miles. Values are typical for 500 kV line:
+-1POLEA LOADA 0.3 5.8 .012 5.0
+-2POLEB LOADB .03 1.6 .019 5.0
+C Large stray capacitance ties the dc side to ground:
+ POLEA 100.
+ POLEB POLEA
+C Load on dc side is parallel 200 ohm R and 100 microfarad capacitance:
+ LOADA LOADB 200.
+ LOADA LOADB 100.
+C One-ohm grounding resistance, for later fault (see DC-49 continuation).

+C 20 August 1998, discovery that Pi-circuits are mishandled leads to addition
+C of the following radial branch off the generator (does not change answers):

+C Bridge circuit consisting of 6 uncontrolled valves (i.e., diodes). Those
+C numbered 1, 2, and 3 feed "POLEA", making it positive with respect to
+C ground. Diodes 4, 5, and 6 feed "POLEB", making it negative.

+C The following card serves to name the switch following it. To see the
+C results of this activity, interactively execute the "SWITCH" command of
+C SPY, sending "EXTRA" for the alternative table. Another point: note
+C the exclamation point, which is needed to hold lower case within A6 name
+C (assuming KINSEN = 1 within STARTUP). No such control for valve six.
