How alternator behavior can be abstracted to a DC model that simulates efficiently. This test harness first ramps the alternator speed linearly from zero to a typical idle speed of 900 RPM. When the generated voltage is sufficient to overcome the forward voltage drop associated with the rectifier diodes, the battery charging current starts to ramp up. The test harness then ramps up the speed to 5000 RPM, and the alternator has to back off the field voltage to maintain the regulated voltage. The model captures the increase in stator resistance as the alternator heats up, this reducing device performance

An interior permanent magnet synchronous machine (IPMSM) used as a starter/generator in a simplified 48V automotive system. The system contains a 48V electric network and a 12V electric network. The internal combustion engine (ICE) is represented by basic mechanical blocks. The IPMSM operates as a motor until the ICE reaches the idle speed and then it operates as a generator. The IPMSM supplies power to the 48V network, which contains the R3 power consumer. The 48V network supplies power to the 12V network which has two consumers: R1 and R2. The total simulation time (t) is 0.5 seconds. At t = 0.05 seconds, the ICE turns on. At t = 0.1 seconds, R3 switches on. At t = 0.3 seconds, R2 switches on and increases the load on the 12V electric network. The EM Controller subsystem includes a multi-rate PI-based cascade control structure which has an outer voltage-control loop and two inner current-control loops. The task scheduling in the Control subsystem is implemented as a Stateflow® state machine. The DCDC Controller subsystem implements a simple PI controller for the DC-DC Buck converter, which feeds the 12V network. The Scopes subsystem contains scopes that allow you to see the simulation results.
