High Frequency LTCC based Planar Transformer
… which has led path to the development of planar based magnetic materials. Nowadays more planar magnetic technology has been employed because it is easier to fabricate them. The planar magnetic is a transformer or an inductor that replaces the wire-wound transformer or inductors which …

Planar transformer isolated DC-DC Converter for Solid-State Transformer
… been increasing through the years. Solid state transformer (SST), which is typically formed by three stages, one being DC/AC inverter, which is controllable, one being medium-frequency transformer isolated converter and the other being AC/DC rectifier, has been developed quickly during past few …

Miniaturization of on-chip passive electronic devices by silicon nitride self-rolled-up membrane microtube nanotechnology
… solve the intrinsic drawbacks of currently used planar spiral platforms for passive lumped elements. A new design platform based on self-rolled-up membrane (S-RuM) nanotechnology that “processes like 2-D and functions like 3-D” is proposed for constructing on-chip three-dimensional (3-D) …

Magnetic and Thermal Design of Litzwire 500 kHz Highpower Planar Transformers with Converging Cooling Duct for “dc Transformer” Resonant Converter Applications
… the design and analysis of two Litz wire transformers for a 500 kHz, 18 kW inputparallel outputseries partial power processing converter (IPOS PPP). Because the two power paths in the IPOS PPP operate as “dc transformers” (DCX), both transformers are designed with the goal of leakage …

Methodologies for Design-Oriented Electromagnetic Modeling of Planar Passive Power Processors
The advent and proliferation of planar technologies for power converters are driven in part by the overall trends in analog and digital electronics. These trends coupled with the demands for increasingly higher power quality and tighter regulations raise various design challenges. Because inductors …
