The optimization of electrical circuits is a difficult and time-consuming process performed by experts, but also increasingly by sophisticated algorithms. In this paper, a reinforcement learning (RL) approach is adapted to optimize a LLC converter at

This paper proposes a portable 11 kW off-board charger for electric vehicles. In the ac/dc stage, a three-phase power factor correction (PFC) in Vienna topology is chosen. The loss and volume of the PFC inductance are calculated over a wide range of

This paper describes an isolated bidirectional half-bridge active-clamp current-fed push-pull DC/DC converter developed for a DC microgrid. A novel modulation scheme is introduced for step-down operation, which decreases the switching losses mainly o

This paper examines an inductive power transfer (IPT) system with a rotary transformer as an alternative solution to slip ring systems for a contactless energy transfer to rotating equipment. A prototype system is set up, consisting of a rotating bal

Inductive power transfer (IPT) systems significantly depend on magnetic coupling and coil characteristics. To achieve maximum coupling in case of an air gap and misalignments, different coil shapes were investigated. Based on this research a special
