Microcontroller family that helps boost efficiency of power electronics devices introduced by Pulsiv
CAMBRIDGE, England – Pulsiv Limited in Cambridge, England, is introducing the OSMIUM Pulsiv OSMIUM microcontroller family for converting AC to DC that involves charging and discharging a small storage capacitor without the need for a power factor correction (PFC) inductor.
This solution delivers high power and efficiency in an compact system design that can help improve overall system efficiency, optimize cost, and reduce energy consumption.
The Pulsiv OSMIUM microcontroller family and supporting components can combine with commodity flyback DC-DC converters to displace LLC solutions.
Pulsiv has demonstrated a universal-input single-switch 150-Watt flyback power supply design that delivers 97.5 percent average front-end efficiency while maintaining 90 percent at 2 Watts. A 240-Watt interleaved flyback is being developed.
The PSV-AD-150 and PSV-AD-250 OSMIUM microcontrollers do not determine output power directly and can be used for applications that require 1 Watt to 10,000 Watts, by adjusting three system components and connecting a suitable DC-DC converter.
Critical components in a Pulsiv OSMIUM circuit operate at low temperatures to extend their expected operating life, even under convection cooling.

By regulating the flow of mains through a charging capacitor, Pulsiv has completely eliminated inrush current, meaning that manufacturers of industrial power supplies and LED lighting products can simplify their designs and reduce the cost of system installation.
Pulsiv OSMIUM technology supports active bridge control, configurable hold-up, X-cap discharge, HVDC output selection, a power consumption indicator and grid failure detection.
