Initiatives to go 'carbon' neutral' such as the '2050 long-term strategy' in the EU, to achieve net-zero greenhouse gas emissions, have sharpened engineers' focus on power conversion architectures and their efficiency. Minimising losses has always been a design engineer's goal anyway; low values directly reduce energy and cooling costs while equipment can be sma

When I first started in the power electronics industry in the seventies, device selection was limited. We were moving from silicon bipolar transistors and rudimentary rectifiers to MOSFETs and better rectifiers. Surface-mount technology and co-packaged ICs with power devices and/or drivers were unheard of and usi

Modern power conversion techniques all push towards higher efficiency for good reason; energy saving is clearly important but there are applications where functionality is also enhanced. Examples would be alternative energy systems such as solar and wind, and electric vehicle chargers where fewer losses equate to shorter recha
