Transient Calorimetric Measurement of Ferrite Core Losses
(2020)2020 IEEE Applied Power Electronics Conference and Exposition (APEC)An accurate and fast transient calorimetric ferrite core-loss measurement method is proposed in this paper. In contrast to electrical measurements, the accuracy of the calorimetric approach is independent of the magnetic excitation and operating frequency. However, an accurate value of the thermal capacitance of the Core Under Test (CUT) is required, which can be achieved, e.g., by measuring the specific heat capacity of the measured core ...Conference Paper -
Optimized Cascaded Controller Design for a 10 kW / 100 kHz Large Signal Bandwidth AC Power Source
(2020)2020 IEEE Energy Conversion Congress and Exposition (ECCE)The control system of a phase-modular three-phase 10 kW / 230 V rms Ultra-High bandwidth series/parallel inter-leaved multi-level AC Power Source (UHPS) for P-HIL applications with 4.8 MHz effective switching frequency is optimized with respect to high bandwidth and low output impedance or output admittance (depending on whether output voltage or output current is controlled), by adding selected and effective enhancements to existing ...Conference Paper -

Quad-Port AC-DC-DC-AC Operation of Isolated Dual Three-Phase Active Bridge Converter
(2021)2021 IEEE Applied Power Electronics Conference and Exposition (APEC)This paper investigates the operation of the Dual Three-Phase Active Bridge (D3AB) converter topology as a multi-port converter, by taking the three-phase ac port and dc port on the primary side (ac(1) and dc(1)) and the galvanically isolated three-phase ac port and dc port on the secondary side (ac(2) and dc(2)) simultaneously into account. The basic working principle of the D3AB topology under multi-port operation and a strategy to ...Conference Paper
