The Mini Hybrid GPU was first developed in 1995 for the UK military in response to the need for a low cost self contained GPU able to produce both continuous DC power for pre-flight/avionics use and short-term high power for turbine starting.
The latest version has been adapted for civil use and is now available for FBOs, regional airlines, and operators requiring versatile remote power at a fraction of the cost of a conventional diesel GPU. It comprises a small highefficiency single cylinder diesel engine able to run on diesel or Jet A1 fuel, direct coupled to a 110 or 230V AC generator. Depending on the specification, this provides continuous AC or DC power with very high amperage for starting turbines or powering aircraft systems for short duration by using either internal batteries or demountable portable DC power packs. A 115 / 200V, 400 Hz version is available to power 400 Hz aircraft systems.
For versatility, the output may be switched between 28 VDC power and 110 or 230 V 50/60Hz domestic voltage depending on customer spec, allowing the GPU to be used as a conventional gen-set. In enclosed spaces such as maintenance shops or hangars, the diesel engine can be shut down and the unit powered directly from any 110/230 V mains supply to provide 28 VDC power without discharging the batteries.
Modular starter packs are an option, instantly delivering peak loads up to 2000 A for the starting of DC regional aircraft large turbine. These optional packs may be used independently for the maximum equipment utilisation and flyway capability.
The Mini Hybrid GPU can be disassembled for easy transport by road or air and supplied in a variety of configurations, and equipped with modular power supplies of up to 150 A continuous output (300 A model coming soon).
