Electromagnetic compatibility and oftentimes PCB trace routing are key participants in the switching-regulator hot-loop phenomenon. The term hot loop is relevant whenever switching regulators and their electromagnetic compatibility (EMC) are ...
A collaborative research project is making use of temperature fluctuations to produce electricity. Generating electricity in unique ways is getting the attention of scientists at the University at Buffalo and MIT. Collaborative research project led ...
The flyback topology is a versatile, widely used, switched-mode power-supply design with some interesting characteristics that brings performance and BOM advantages to many applications. The flyback design is a switched-mode power supply (SMPS) ...
Applying the physics principle of radiative sky cooling, a team was able to harvest a small but useful amount of energy from the cool night sky using a simple, low-cost, non-critical arrangement. Approaches to harvesting “free” energy ...
David Megaw and Bruce Haug, Analog Devices Design Note Introduction A common dc-to-dc converter problem is generating a regulated voltage when the input voltage can be above, below, or equal to the output that is, the converter must perform both ...
Question: Where should the coil go? Answer: Switching regulators for voltage conversion use inductors for temporarily storing energy. These inductors are often very large components and must be positioned in the printed circuit board (PCB) layout ...
I worked on a quasi-resonant energy converter, which in an extremely simplified form looked like the one shown in Figure 1. Figure 1. This is a simplified design for a quasi-resonant push-pull inverter. A push-pull pair of power MOSFETs would turn ...
The power factor corrector (PFC) front end of an off-line power supply is subject to the operating frequency limitation caused by the Miller Effect of its associated power MOSFET. This effect is a property of any transistor configuration with a ...
This charge-pump circuit, using just a few diodes and capacitors, ups the input voltage by a factor of 1.5 in contrast to the usual voltage-doubling output. Micropower product designs sometimes require a simple, inexpensive voltage booster to ...
Syntiant, an Irvine, California-based startup with big name backers like Intel and Microsoft, said its custom chips could be used to push Amazon's Alexa into smaller, battery-powered devices like wirebles and wireless headphones that wake ...
