- This paper deals with PSPICE simulation of automotive AC-DC macrocommutator generators, in which are commonly equipped internal combustion engines and/or external combustion engines of civil and military automotive vehicles. In the beginning a physical model of automotive AC-DC macrocomutator generators is created. Next, on the basis of this physical model, a mathematical model of automotive AC-DC macrocommutator generators has been formulated, taking into account controlled nonlinear self-inductances and mutual-inductances. The created physical model for simulation of an automotive AC-DC macrocommutator generator with a diode macrocommutator (macroelectronic commutator) can be used, not only for the estimation of power quality (PQ) indices in these on-board 42 VDC AC-DC commutator generators, but also for the investigation of new configurations of macrocommutators with fully-controllable uni- and/or bipolar electrical valves (e.g., with MOSFETs, IGBTs or MCTs). To estimate the AC output of the macrocommutator, as regards a power quality (PQ), the Fourier analysis of a phase current has been used. It can be concluded from the simulation results that a significantly lower harmonic content, especially, in the low-frequency range can be obtained using fully-controllable macrocommutators. Simulation results are presented, not only for an automotive electrical machine, but also for an AC-DC macrocommutator. The PSPICE simulation makes it possible to observe the static and transient oscillograms of different physical values (e.g., voltages and currents) which are not measurable in real electrical machines.
