The "inverterless" alternator is designed with a high back-emf voltage and high reactance, and thus operates as a constant current source over much of its wide constant power operating speed range. In this configuration, a switched-mode rectifier is used to regulate the DC output voltage and current, which avoids the complexity and high cost of an inverter. The analysis of the modelling and performance of interior PM machines for this inverterless topology is described and experimental results are presented for a 6kW concept demonstrator machine showing an outstanding constant power speed range.
