[110] Multi-Loop Control for Quasi-Resonant Converters
Very high frequency quasi-resonant converters can benefit from current mode control. Different techniques are used to generate clean waveforms at up to 10 MHz.
[109] The Rebirth of the Electric Car
In 2005, all of the major car manufacturers gave up on their electric programs. They were jolted awake again by Tesla who commercialized the TZero technology. You can also read about why the hydrogen economy is a non-starter.
[108] Custom Transformers – Leakage Inductance Considerations
One equation governs the saturation of a transformer, but the leakage inductance provides strong direction to a design.
[107] Alex Lidow at APEC 2019
A provocative talk from Dr. Alex Lidow on the "Death of Silicon"
[106] Custom Transformers – ONE Design Equation
As with inductors, the design of a transformer is governed by a single design equation. Obey this, and the path to creation of new designs is clear
[105] Designing Custom Inductors
Inductor manufacturers have made great progress in the families of standard parts. The selection of off-the-shelf parts in this category have increased dramatically in the past 10 years.
[104] Current Mode Control Book
Updated version of Dr. Ridley's definitive Current-Mode Control Book
[103] Custom Inductors – Applying the ONE Design Equation
Dr. Ray Ridley continues his discussion on the ONE design equation.
[102] Custom Inductors – ONE Design Equation
Dr. Ray Ridley discusses his introduction into Power Electronics. An early foray into design optimization software revealed a curious fact about magnetics design - there is only ONE design equation that must be obeyed.
[101] Magnetics Design – Simple or Complex?
What do you need to build good magnetics? A PhD, or practical experience?
[100] Magnetics Design Part I - Standard or Custom?
Magnetics represent the most ancient of technologies used in modern electronics systems.
[099] Modern Magnetics Design
This article gives an example of how profound proximity effects can be.
[098a] Vorperian's Coupled-Sepic Analysis Notes
Dr. Vorperian's hand-written analysis of the tightly-coupled sepic converter.
[098] Small Signal Modeling of the Tightly-Coupled Sepic Converter
Dr. Vorperian's analysis of the tightly-coupled sepic converter.
[097] Linear Circuit Model for Predicting Magnetics Winding Proximity Losses
A linear circuit model is derived which will show complex proximity effect losses for arbitrary waveforms.
