More on: Infineon's over-current blocking FET

Infineon Technologies is to develop a two-terminal semiconductor device that acts as a circuit breaker for hundreds of volts and amps: doubling the performance of its mains-voltage super-junction mosfets along the way.

The aim is to replace electromechanical circuit breakers with something faster.

“A circuit breaker can…

Boost converter goes multi-phase for less ripple

Linear Tech has gone two phase to shrink components in a monolithic battery-powered boost converter.

Common in high-current buck (step-down) converters, multi-phase operation is uncommon in step-up converters.
“Dual-phase operation significantly reduces peak inductor and capacitor ripple currents, minimising component size while delivering lower…

Raytheon battery monitor tested by military

Raytheon’s battery monitoring system (BMS) will be used in military vehicles to help extend the life of batteries, reduce the number of unnecessary battery replacements.

Battery power is used to drive engines during so-called ‘Silent Watch’ periods.

The system is designed to revert to a hibernation mode when…

Composite insulators improve transformer safety

Resin high-voltage insulators with a composite casing can mitigate explosion, fire and leakage in high power transformers, according to Paolo Cardano, transformer expert at power component maker Alstom.

Around a quarter of the insulators, known as ‘bushings’, currently sold by Alstom are of the resin type but Cardano anticipates…

Big transformers go veggie

Vegetable oil-based electrical fluids will increase transformer safety and minimise environmental impact compared with traditional mineral transformer oil, according to oil company Repsol.

“We have to accept that petroleum reserves are finite,” said Repsol technologist Ernesto Diestre. “Repsol is seeking a guarantee of a secure supply, with lower emissions…
