Applications of Loop Analysis - Super Mesh Technique

Loop analysis is a powerful tool in circuit theory that is used to analyze and optimize feedback control circuits, resonant circuits, filters, power electronics circuits, and communication circuits. The Super Mesh technique is an advanced method of loop analysis that is used to analyze circuits with multiple current sources. The Super Mesh technique is based on the principle of Kirchhoff's Current Law (KCL) which states that the sum of the currents entering a node must equal the sum of the currents leaving the node. This principle is applied to the circuit in the form of mesh equations, which are used to calculate the currents flowing in the loops of the circuit. The Super Mesh technique is used to analyze circuits with multiple current sources by creating a single mesh that encompasses all the current sources in the circuit. This is done by combining the meshes that contain the current sources into a single mesh, which is referred to as a Super Mesh. The Super Mesh is then used to calculate the currents flowing in the loops of the circuit. To use the Super Mesh technique, the circuit must be broken down into individual loops, each of which is assigned a current. The current flowing in each loop is then expressed in terms of the other loop currents and the current sources in the circuit. The resulting equations are then solved simultaneously to find the values of the loop currents. The Super Mesh technique is particularly useful in the design and analysis of power electronics circuits, such as DC-DC converters and inverters, which often contain multiple current sources. The technique can be used to analyze the behavior of the circuit and optimize the feedback control circuitry to improve performance. For example, consider a circuit that contains two current sources, as shown in the diagram below: Super Mesh Example Circuit To use the Super Mesh technique to analyze this circuit, we first create a Super Mesh that encompasses both of the current sources, as shown below: Super Mesh Example Super Mesh The current flowing in the Super Mesh is expressed as the sum of the currents flowing in the two individual loops, as shown below: I1 + I2 = 2A The current flowing in Loop 1 is expressed in terms of the other loop currents and the current source values as follows: 10V - I1 * 3? - (I1 - I2) * 2? = 0 The current flowing in Loop 2 is expressed in terms of the other loop currents and the current source values as follows: (I2 - I1) * 2? - I2 * 4? + 6V = 0 Solving these equations simultaneously, we get: I1 = 1.33A I2 = 0.67A Using the Super Mesh technique, we can analyze the behavior of this circuit and optimize the feedback control circuitry to improve performance. In conclusion, the Super Mesh technique is a powerful tool in circuit theory that is used to analyze circuits with multiple current sources. The technique is particularly useful in the design and analysis of power electronics circuits, such as DC-DC converters and inverters. By breaking down the circuit into individual loops and using mesh equations to calculate the currents flowing in each loop, the Super Mesh technique can be used to analyze the behavior of the circuit and optimize the feedback control circuitry to improve performance.
