Experience


Global Power Electronics Design House, GPDH, has the expertise, experience, knowledge, industry contacts, equipment and tools to carry out all phases of most projects from research through to providing manufactured products.

We are very experienced in executing projects with multi-disciplinary requirements such as simultaneous research, industrial design, mechanical design and power electronic/software design followed by prototype and volume manufacture.


We provide low-volume Prototyping and Assembly services, but transfer the well documented design to a Contract Electronics Manufacturer for production on the following subjects.

Switch Mode Power Supplies , Battery Charger for Telecom and Motive power

Power Electronics, Solar Cell and Wind power control system

Power Conversion AC to DC, DC/DC isolated and non isolated high frequency Soft switching convection and fan cooled system development

Power Management Systems, Fuel cell, LI-ON powered charger design


Our own expertise covers general electronic developments mentioned above plus:


A sound understanding of the theory and application of physical principles

Analytical modelling using various tools e.g. MathCAD, PSpice, and Excel

Mechanical design aptitude, CAD software and PCB design

Industrial design experience and close links to several Industrial Design studios

Regular use of 2 electronic sub-contract manufacturers

Close contacts with various mechanical manufacturing companies e.g. CNC machining, laser cutting, sheet metal, welded fabrications in aluminium, stainless steel and ferrous metals
