Fast electric circuit models

Description

Manatee e-NVH software includes fast electrical circuit models to perform voltage-driven electromagnetic simulations. These models can be used to quickly estimate current levels from voltage inputs without transient simulations. They are based on harmonic Equivalent Electrical Circuit (EEC) in steady state, describing the voltage/current transfer functions with equivalent resistances and inductances.
 
 

Application

Fast EEC models can be used by electrical engineers to directly input the voltage control law. They are especially useful for induction machine (input of slip and phase voltage as a function of operating point) and for the simulation of PWM voltage inverters.
