The goal of this tutorial is to present the modern soft switching technologies as an avenue to increase the efficiency and power density in power convertors.

Soft switching topologies have become popular in many applications in the last thirty years. Though we have such a long tradition in soft switching technologies, some of these have added too much complexity and their practical use becomes questionable. Read more…

Description:
The seminar will present a comprehensive overview of the modern magnetic technologies presently used in power conversion and new trends in magnetics aimed in addressing the new demands in power conversion. In the quest for higher power densities and higher efficiency magnetic technologies were forced to adapt and new magnetic structures were developed.

The seminar will start by presenting several key characteristics of magnetic transformers such as leakage inductance, stray inductance, inter-winding and intra-winding capacitances and their impact on power conversion performance. Methods of measuring and controlling these parasitic elements are also presented.  Read more …


Press release April 2018

Rompower latest technologies  in power conversion reduce the size of the 65 W laptop adapter to the size of an AC power plug

 

 

65W

η≈94%

27W/in3

The ac/dc adapter technology has evolved over the last years and presently the technologies developed by Rompower Energy Systems Inc., increase the efficiency from 88% to 94%, the highest in its class. This increase in efficiency decreases the power dissipation by more than 50% making the adapter to run much cooler. Lower heat dissipation allowed Rompower engineers to reduce the size of a 65W laptop adapter to a tiny volume of 2.3 inc3 (38.5cm3) comparable with the AC power plug while eliminating the bulky AC cable.

We always push ourselves to be at the forefront of power conversion technology, “says Ionel “Dan” Jitaru the founder and CEO of Rompower Energy Systems Inc. Read more…
