MESH CURRENT METHOD

Ertuğrul Eriş & Berrak Öztürk

rroteus objectives
RROTEUS OBJECTIVES
  • HOW TO INSERT DEPENDENT SOURCES TO CIRCUIT SHEMATIC
  • HOW TO FIND OUT ELEMENTS’ CURRENTS IN TERMS OF MESH CURRENTS (SUBSTRUCTION OPERATION)

Ertuğrul Eriş & Berrak Öztürk

circuit to be analyased by proteus simulation
CIRCUIT TO BE ANALYASED BY PROTEUS SIMULATION

Ertuğrul Eriş & Berrak Öztürk

adding resistor elements
ADDING «RESISTOR»ELEMENTS

Ertuğrul Eriş & Berrak Öztürk

adding dc voltage source element
ADDING «DC VOLTAGE SOURCE» ELEMENT

Ertuğrul Eriş & Berrak Öztürk

adding current controlled current source element cccs
ADDING «CURRENT CONTROLLED CURRENT SOURCE ELEMENT» (CCCS)
  • Could give a name to the element by writing here

Ertuğrul Eriş & Berrak Öztürk

topology
TOPOLOGY

CCCS has a 4 pin

Ertuğrul Eriş & Berrak Öztürk

topology cccs connection 1
TOPOLOGY: CCCS CONNECTION-1

Controlling current (v3 source’s current) should also flow the control terminals of the CCCV element.

Ertuğrul Eriş & Berrak Öztürk

topology cccs connection 2
TOPOLOGY: CCCS CONNECTION-2

current flow reference of both V3and CCCS elements should be in the same direction

Ertuğrul Eriş & Berrak Öztürk

topology cccs connection 3
TOPOLOGY: CCCS CONNECTION-3

Non of the terminals of the CCCS elements shoul be in open air!

outputs current probes
OUTPUTS: CURRENT PROBES

What happens if an element’s current flow reference

and probe current reference directions are opposite?

Ia, Ib, Ic

  • Which element’s currents is
  • the same as a mesh current?
  • What is Iv3
  • in terms of mesh currents?

Could there be a mesh current

which cannot be measured directly in general?

Your answer for this circuit?

If the answer is «yes» for general case, How?

Ertuğrul Eriş & Berrak Öztürk

outputs voltage probes
OUTPUTS:VOLTAGE PROBES
  • Voltage probe directly measures node voltages!
  • not the elements voltages (exceptions?)
  • How could find the element voltages?

Ertuğrul Eriş & Berrak Öztürk

simulation type analog
SIMULATION TYPE: ANALOG

Ertuğrul Eriş & Berrak Öztürk

adding currents and votages of which waveforms to be observed
ADDING CURRENTS AND VOTAGES OF WHICH WAVEFORMS TO BE OBSERVED

Add trace

How to choose

different

y-axis for the

voltages and

currents?
