Pulsiv signs major Chinese power supply maker

Chinese power supply maker Salom is developing a 150W power supply platform based on the recently launched Osmium technology from Pulsiv in the UK.

Pulsiv has developed an entirely new method of converting AC to DC that enhances conventional flyback topologies with no inrush current at both high and low-line input voltage.

“Collaborating with Salom has shown what’s possible when an innovative power supply company deploys Pulsiv OSMIUM technology. Our combined expertise has already achieved results beyond original expectations and there’s still scope for further optimisation,” said Darrel Kingham, CEO of Pulsiv.

“Salom’s unique platform delivers consistently high efficiency while reducing system cost and brings the electronics industry one step closer to making sustainable product design the default choice.”

The deal is important for Pulsiv as Salom is a major ODM supplier of power supplies to leading companies such as Dyson, Motorola and Philips and has built over 3bn supplies since its founding in Taiwan in 1972.

Pulsiv’s microcontroller-based Osmium algorithm delivers a flat efficiency profile from 10W all the way through to 150W without using GaN or other costly ancillary components and helps to reduce the size of the power supplies by reducing the size of the inductor.

The importance of this architecture and reduction in power loss over the whole load range cannot be understated for applications with a variable load, says Andy Richardson, Vice President Business Development at Salom Europe. He points to lower cost complex resonant PSU architectures and lower losses at lighter loads resulting in reduced input power and lower operating temperatures which extends product life.

A key advantage for Salom as an ODM is that this means a single PSU can now be used to support multiple applications rather than an optimised supply for each, significantly reducing the complexity of its supply chain for customers.
