PSIM-AC PSIM-DC PSIM-5V
7.0:
Applications (continued)
Application 1: Basic Small Network Connection.
• Power supplied to network from PC via network card, no PSIM used.
• Modules connected using standard communication cables.
Volt drop total in mV = cable 1 + module (3 off) + cable 2 + module (3 off)
= (15.2 x 6) + 0.04(6+5+4+3+2+1) + (15.2 x 3) + 0.04(3+2+1)
= 138 mV
Then approximate voltage at end of network = nominal supply voltage - calculated volt drop
= 5.1 - 0.138
= 4.96
