Power Assemblies

GD Rectifiers is one of the leading manufacturers of Power Assemblies, our team have a vast range of experience in working with customers to create customised power assemblies to meet the tightest requirements. We provide support and design expertise to customers requiring more than basic semiconductor components. 

We specialise in the design of assemblies such as rectifiers, regulators, inverters, selenium suppressors, firing circuits/trigger modules and single phase, three phase and hex phase assemblies. We utilise the experience of our mechanical, electrical and power electronics engineering experts to test, design and deliver the best technology in our products. 

We offer a large range of services and solutions from standard off-the-shelf power assemblies, to assembly components, custom designs and traction refurbishment services. We manufacture a wide range of standard power assemblies with 24 designs available from three configurations. All configurations of high power single-phase, three-phase and hex-phase diode and thyristor rectifier assemblies from 5kW up to 5WM are designed and manufactured in house, incorporating bespoke clamping systems and thermal management solutions.

We offer a broad range of assembly components including semiconductor device clamps and heatsink profiles for maintaining the thermal and electromechanical integrity of the components which can be used for diodes, thyristors, GTOs and IGBTs. GD Rectifiers provides a traction refurbishment service, we work with several companies to manufacture and refurbish rectifiers, with over 10 years experience of rail maintenance with our semiconductor capabilities we can help customers reduce maintenance costs.  

Solid state semiconductor technology used in our power assemblies provides customers with standard and custom design solutions for most industrial power applications.

From the traditional fields such as high powered high voltage rectifiers for charging, resistance welding, plating, heating, lighting, cathodic protection, magnetic supplies, pulse power, through frequency control, variable speed drives, choppers, inverters, to modern day green energy saving applications such as, wind, solar and tidal energy.
