Thyristor Controller Firing Methods

by Madison Solutions | 7 August 2017 | Latest News & Information

What Are The Most Common Thyristor Firing Methods?

Thyristors are controlled by sending the correct signal to the gate connection of the device. It will then continue to let current flow until the gate signal is removed and the voltage through it reaches zero. There are two main methods of firing the thyristors:

Thermal Properties of Aluminium and Copper

The efficiency of a thermal management system can be considered to be a measure of how well the system conducts heat away from the source(s) to the outside world. Commonly used materials in heat sink construction, such as Aluminium and Copper, have defined thermal properties, which help to identify the

Silicon Carbide (SiC) Increasing Use In Power Electronic Devices

by MWilliams | 26 June 2017 | Latest News & Information

Since the early sixties, Silicon has been used as a semiconductor “switch” and the quest for higher switching frequencies, greater power densities, higher blocking voltages, lower losses, increased operating temperatures etc. has led to the introduction of Silicon Carbide (SiC) and other wide band gap materials in power devices.

Wide Band Gap Semiconducting Materials

Silicon Carbide is

SNUBBER & MOV CIRCUITS FOR THYRISTOR ASSEMBLIES

by MWilliams | 12 June 2017 | Latest News & Information

What are snubber & MOV circuits for?

Snubber circuits are used to control voltage transients that could falsely turn on or damage a thyristor. The object of the snubber is to suppress the voltage transients and ringing that occurs when the thyristor is switched by providing an alternate path for the current flowing through the circuit’s

Efficient Cooling Of IGBT Power Modules

by MWilliams | 17 May 2017 | Latest News & Information

Optimising The Thermal Conduction Path From Chip To Heatsink

IGBT’s (Isolated Gate Bipolar Transistors), in common with all power semiconductor devices, are not 100% efficient and most of the “lost” power manifests itself as a dramatic temperature rise of the silicon chip(s). The temperature rise needs to be managed as efficiently as possible by minimising the

What to consider when choosing a heat sink?

by MWilliams | 19 December 2016 | Latest News & Information

A heat sink is a heat exchanger which works passively in order to transfer the heat generated by a device to a more fluid medium, such as air or liquid, to increase the performance of an electronic device. The most commonly known devices that use a heat sink are computers and semi-conductors. The heat sink

Advances in Power Semiconductor devices

by MWilliams | 29 November 2016 | Latest News & Information

What is a Power Semiconductor?

A power semiconductor is used to switch or control power (or current) in electrical circuits. These include the power diode, power MOSFET, Bipolar Junction Transistor, Thyristor and Insulated Gate Bipolar Transistor (IGBT). They can be categorised as either 2-terminal, or 3-terminal devices.

Power diodes are 2-terminal devices, made up of two type
