Bridge Average Value Model of Modular Multilevel Converter
The speed-up simulation model of modular multilevel converter (MMC) is the basis for the research of voltage-source converter high-voltage direct-current (VSC-HVDC) system. Among many models, the bridge Thevenin model of MMC is the most widely used.

According to the conventional perception among engineers, once a circuit is reduced to its Thevenin or Norton equivalent, the voltage and current may be determined only at the load, but not in the remaining parts. The other voltages and currents that exist in the remaining parts of circuit should be determined by returning to the original circuit ...

An active Thevenin equivalent circuit approach to problems with non-linear circuit loads
The analysis of electromagnetic coupling in nonlinear circuits requires a bidirectional, fully consistent approach. Nonlinear responses of semiconductor devices in electronic circuit components can change the impedances seen at circuit nodes, changing the boundary conditions encountered by impressed electromagnetic fields, and thus changing the ...

Analysis of a Three Phase Induction Motor Directly from Maxwell's Equations
The torque developed in a three phase AC squirrel cage motor is usually expressed in terms of resistances and reactances of the stator, the rotor, and the motor as a whole. We use Maxwell's equations to find the torque in terms of geometrical parameters.
