“…As can be seen from Figure 6, the model block consists of four main parts based on the equations previously stated. These are an electrical part for the stator output currents based on ( 8) and rotor field input current based on (9), respectively, an electro-mechanical part for the alternator electrical load torque based on (17), a mechanic-to-electrical part, which produces the three-phase stator dependent voltage sources based on ( 10) and ( 11), the rotor field dependent voltage source based on (13) and back emf on the basis of ( 14), and a mechanical part according to Figure 3 for the alternator speed. The proposed model contains two features, one of which is that the stator and rotor field windings are circuitbased.…”

“…Except the DC excited wound field, the permanent magnet-assisted CPA (PMa-CPA) has permanent magnet placing into the rotor, so that the torque density and power efficiency can be improved. In addition to connecting to the diode-bridge rectifier to supply power to vehicles, it has been shown that the switched-mode rectification with pulse-width modulation (PWM) coupled with some dedicated controls can provide great improvements in the transient response, efficiency, and power capability in previous works [16,17]. A variety of integrated circuits (IC), such as Freescale TC80310, ONSEMI CS3361, ST L9409, and ST L9914, have been designed for the voltage regulation in various automobiles [18][19][20][21].…”

This paper presents the phase-variable modeling of a permanent magnet-assisted claw-pole alternator in PSIM simulation software tool with the performance compared with a claw-pole alternator model, which is a special case of the permanent magnet-assisted claw-pole alternator model with the rotor permanent-magnet flux constant setting equal to zero. The constructed model can be simulated as a real alternator directly connected to a diode-bridge rectifier or switch-mode rectifier circuit for the integrated power application system simulation analysis. The proposed model contains two features, one of which is that the stator and rotor windings are circuit-based. The other one feature is that the mechanical torque input is based on a mathematical function. In this model, the rotor position-dependent variable inductor is replaced by a separate voltage source according to the voltage source absorption theorem. The simulation shows that the proposed model has faster torque step response and higher power efficiency than the claw-pole alternator model. The proposed model can be employed to the application of the control design and simulation study of voltage regulation in automobiles. The simulation results with 15-V command and the load sudden change verify the correction of the proposed model.
