IGBTs – fast switching - high current & high voltage

by MWilliams | 7 November 2016 | Latest News & Information

What is an Isolated Gate Bipolar Transistor?

Before the development of the IGBT, power electronics engineers had two types of device available for higher frequency switching – the Bipolar Junction Transistor (BJT) and the Metal Oxide Field Effect Transistor (MOSFET). Both devices could switch at higher frequencies than Thyristors (or SCRs) but each had some

Higher power in smaller spaces

Ever increasing demands for higher power density solutions have driven designers of high power electronics equipment to seek more efficient and effective cooling systems. The requirement for large surface areas, where convection or forced air cooling is used, defines the space which will be taken up by the thermal management system.

Thyristor Controlled Rectifiers

by MWilliams | 5 September 2016 | Latest News & Information

Why use thyristors in high power rectifiers?

Power grid networks deliver electricity as AC (Alternating Current), but some key applications, such as electric vehicle battery charging and Light Rail transport systems, require DC (Direct Current) for economic and efficient operation. For example, standard Rail DC voltage systems operate across Europe, nominally at 600V, 750V, 1500V and

Thyristor control for AC heater systems

by MWilliams | 11 August 2016 | Latest News & Information

AC Heater Systems Control Requirements

Simple AC power systems are used widely in industrial heating applications. In order to provide a properly regulated temperature for the process in question, the supply of power to the heater element needs to be switched on and off to maintain a given temperature level, minimising peaks and troughs. At its

What makes a good Heat Sink?

by MWilliams | 29 July 2016 | Latest News & Information

A heat sink is not just a reservoir for thermal losses

Most modern power electronics devices require controlled temperature environments, in order for them to function correctly. If the device overheats, the performance can be impacted, or in worst cases it fails and can become a safety hazard. The heat sink provides the pathway for heat
