Interleaving in synchronous rectifiers can lead to reduced losses in both the active and passive components. However, this depends on selecting the correct number of phases and the correct phase inductance for a particular application and requirements. In this paper optimizing the number of phases and the phase inductance is considered to maximize theâ€¦ (More)

The integration of an electrical machine and power electronics promises many benefits, the largest being an increase in power density. The use of system integration may lead to an increase in loss density and local or component temperatures. For this reason much attention needs to be paid to the thermal design aspects of the system. In the aerospaceâ€¦ (More)

This paper proposes the use of a three-phase four-leg (3P4L) converter in combination with an LCL filter for the inverter stage of a solid state transformer (SST). This configuration gives full control over the line-to-line, as well as the line-to-neutral voltage and currents, while providing exceptional harmonics mitigation. A procedure to calculate theâ€¦ (More)

In this paper, a very high power density DC/DC converter module for automotive applications is investigated. The 14-V/42-V converter is specified to operate at a power level of 2.1 kW with a water cooled heat sink at 85/spl deg/C. The design and implementation of very high density passive components are discussed. Using the results of the passive componentâ€¦ (More)

Passive components, and inductors, in particular, contribute greatly to the overall volume of power electronic converters. These components are normally packaged individually with little concern for the overall system. For high-density switching power supplies it is imperative to minimize the volume to as great an extent as possible which implies that theâ€¦ (More)

Power electronic systems that are implemented in the automotive environment are expected to operate under harsh electrical and thermal conditions while achieving high power densities. One example of such a power electronic system is the bi-directional 14/42 V DC/DC converter that is utilized in the dual voltage networks of ultra modern vehicles. This paperâ€¦ (More)

Power electronics is finding increasingly more applications in high temperature environments where power density is also a driving factor. The engine compartment of a passenger vehicle is one such example. In this paper, an integral thermal, electrical, and mechanical design of a high power density dc/dc converter operating in the thermally harsh automotiveâ€¦ (More)

There is ever increasing interest in system integration in power electronics. However when asked what exactly system integration is, the answers vary greatly. In this paper, system integration in power electronics is considered, both theoretically and practically. This paper shows that system integration is a process that any correctly functioning powerâ€¦ (More)

It is widely recognized that significant energy savings could be expected through a widespread use of variable speed drives in motor driven systems. In order to widely implement this concept, the size and cost of the power electronics in drives are the key factors. One of the demonstrator programs of European Center for Power Electronics (ECPE) is focussingâ€¦ (More)
