Description
Summary:The paper describes the development and testing of a generator and power electronic interface for use with an IC engine in the auxiliary power unit (APU) of a series hybrid electric vehicle. The output of the permanent magnet generator is rectified and passed through a DC/DC buck converter before connection to the main DC bus bar. Such an arrangement allows the APU to be operated at variable speed and variable power so as to maximise engine efficiency. The tests show that the generator has an efficiency of just under 90% and the DC/DC buck converter and rectifier a combined efficiency of over 95%. The paper describes the generator and power electronic interface and the design interactions between the two.
