Thyristors and IGBTs Explained

by MWilliams | 21 February 2018 | Latest News & Information

Thyristor Controllers

Thyristor controllers are designed to control the battery heat of HVAC systems and the resistive loads within electric furnaces. Most of the time Thyristors will be involved when handling high currents and voltages, and often when control over alternating currents is needed. They are also used for power supplies for digital circuits; in case

Thyristor Controller Firing Methods

by MWilliams | 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:

Zero Voltage Crossover Firing Read More

Selection Of Heat Sink Materials

by MWilliams | 13 July 2017 | Latest News & Information

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

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
