Advanced DC-DC power conversion topologies and mathematical analytical methods [PDF]
, 2019 224 p. In modern technology, power conversion equipment is very important and is now used in a great variety of products. The corresponding equipment can be divided into four groups, ac-ac converters, ac-dc rectifiers, dc-dc converters, dc-ac inverters. From recent reports, the production of dc-dc converters occupies the largest percentage of the total

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures
Advanced Engineering Materials, EarlyView.This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed
