A wide range of modern low voltage power electronic (PE) devices feature sophisticated controls, which aim to improve device performance and ensure better regulation of grid-side ac currents. The implementation of these controls is expected to result in increased device efficiency, improved controllability, higher operating power factors and reduced harmonic emissions. The interactions of individual...
This paper presents results of comprehensive tests of 18 different on-board electric vehicle battery chargers (EVBCs), representing the majority of currently available passenger-car-type EVs in the European market. The presented analysis compares the harmonic characteristics of EVBCs, concentrating on the impact of variations in supply voltage magnitude on emission of low frequency harmonics, as well...
This paper presents the results of testing and analysis investigating impact of operating conditions on harmonic and interharmonic emission of PV inverters. Tests include typical supply voltage distortion and source impedances. Measurement procedures and metrics recommended by standards for evaluating harmonic and interharmonic distortion are discussed. Finally, it is investigated how the Maximum...
