Infolytica Magnet 7.8 Infolytica Corporation released new versions of their industry-leading MagNet, ElecNet, ThermNet and OptiNet simulation software. There are many significant improvements and new features in this release, including improved nonlinear material treatment in AC/time-harmonic simulations and expanded circuit modeling tools for complex control systems. A virtual prototype that is increasingly realistic – that is the driving force behind the improvements and new features in MagNet, ElecNet, ThermNet and OptiNet v7.8. The suite of computer aided engineering software can handle the most complex electromagnetic and electric field simulation requirements. Accounting for Switching Effects Switching effects in nonlinear inductors, transformers and rotating electric machines can be analysed within MagNet 7.8, by including current and voltage controlled switches. Accounting for switching effects, in addition to core nonlinearity, gap and 3D effects, will significantly improve the design of inductors used in switch-mode converters and power supplies, and the design of wireless power transfer coils. A 3D MagNet model incorporating controlled switches in its circuit can fully consider these effects. For example, the following 27 kW boost converter circuit steps-up the battery voltage from a DC bus voltage of 200 V up to 650 V, for an electric vehicle drive. The PWM driven voltage controlled switch regulates the output voltage, and can be used to analyze the effect of switching frequency on inductor losses. A current controlled switch can be used to regulate the inductor or load current.
