[112] The Power of Dowell’s Equations and Curves
The standardized curves of Dowell’s equations are a superb tool for designing better high-frequency magnetics. A careful balance of layer count and wire or foil count is needed to reach an optimum design.
[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.
