High Frequency Magnetic Core Loss Study
The core used to build power inductors and transformers are soft magnetic materials. When there is alternating external field, the magnetic moments rotate and consume energy, which is the core loss. The core loss depends on the AC flux frequency, amplitude, waveform, DC bias and temperature. These …

Modeling magnetic core loss for sinusoidal waveforms
… model to accurately estimate or explain Core Power Losses (CPL). Theoretical advances in magnets led to many model proposals, but as these models where experimentally examined, they quickly lost their validation. Many of the current models use manufacturer's material estimates to form …

Design and evaluation of a very high frequency dc/dc converter
… presented, which provides rapid startup and low-loss operation. The converter regulates the output using high-bandwidth on-off hysteretic control, which enables fast transient response and efficient light load operation. The low energy storage requirements of the converter allow the use of …

Very High Frequency Integrated POL for CPUs
… a smaller footprint occupation, and the hybrid core structure for non-linear inductance control. Moreover, as an important category of the POL converter, the voltage regulator (VR) serves an important role in powering processors in today's electronics. The multi-core processors are widely used …
