Power assemblies designed to your specification, budget and application

Power Assemblies by GD Rectifiers

GD Rectifiers has more than 55 years of experience in the design, manufacture and assembly of high-power semiconductor assemblies. We offer power semiconductor assemblies designed to your specification, budget and timescales. 

Our power assemblies are designed and manufactured by our expert team of engineers and are made using power semiconductors from our partners, including IXYS, Westcode, Semikron and Dynex.

We combine our state-of-the-art engineering expertise with industry-leading semiconductor technology from the world’s leading brands. We utilise our approved semiconductor suppliers’ range of diodes, thyristors, IGBT modules and MOSFETs combined with our bespoke thermal management solutions, providing a value-added product designed to suit your requirements.

The semiconductors we use feature a wide variety of topologies and we can convert AC/DC, AC/AC, DC/AC and DC/DC to suit your specification.

We offer a wide and varied range of industry-leading power assemblies using the latest engineering technology. Our power semiconductor assemblies deliver performance and reliability for crucial customer applications, including: AC drives, DC drives, bridges, regulators, soft start, energy optimisers, telecommunications, UPS and SMPS.
