Realizing an isolated three-phase Power Factor Correction (PFC) ac-dc converter as a phase-modular system, i.e., by star-connecting three single-phase PFC rectifier front-ends with individual isolated dc-dc converter stages generating a common dc out

Multiport power conversion topologies provide the capability of multiple independent converters with a single transformer having multiple windings (i.e., ports) potentially increasing power densities and enabling flexible (and bidirectional) power ro

A three-phase ac-dc converter with high-frequency isolation can be realized as a phase-modular system by using three single-phase Power Factor Correction (PFC) rectifier modules with isolated dc-dc converter output stages, which advantageously allows

A frequency-elastic drive mode for a sucker rod pumping system is introduced to reduce its polished rod peak loads and the total energy consumption. Numerical modeling and an extensive field test verify the concept. The frequency-elastic drive mode i

Pre-charging of DC-link capacitors limits the inrush current when connecting a power converter to the grid. In its simplest form, this can be realized with a relay parallel to a resistor and a diode as shown in [1] and [2]. This digest proposes an al

In contrast to common 3-phase topologies, DC-link capacitance can be reduced by combining input power after the DC-link using a multi-port transformer and suitable control. Initial results of this approach demonstrate stable 12 kW output power using

Thermal management becomes critical as loss-related component parameters become more highly temperature dependent. Although thermal simulation based on component losses is common, this work proposes closing the loop between electrical and thermal sim
