New PFC Architecture is 90% Efficient Down to 2 Watts

Pulsiv CEO Darrel Kingham

  The introduction of digital control to the power industry has gone a long way to make our designs more efficient. Being able to accurately monitor and actively control the circuit may add a little cost and complexity to some designs, but the outcome is generally worth it. Even though digital control

Dispelling a Myth – GaN and Motor Drivers

Marco Palma, Director of Motor Drives Systems and Applications at EPC

There is a commonly held belief in the industry that GaN devices are wasted on inverters for electric motors. After all, if the performance of the system is restricted by the use of a 20KHz PWM, then there can be little benefit in using a material that gains the majority of its advantages from faster switching sp

­Solid-State Batteries Coming Closer to Commercialization

Adden Energy will work to scale the battery up to a palm-sized pouch cell, and then upward toward a full-scale vehicle battery in the next three to five years

Solid-state batteries offer all the upsides of the Li-ion batteries that electric vehicles use, but have much fewer downsides. The time it takes them to charge can be measured in minutes, rather than hours, and because they don’t have a liquid electrolyte, they are much safer and far less prone to bursting in
