Static Frequency Converter

Supplier: Thycon

Thycon’s GPCU Centralized Ground Power Supply is a dedicated 400Hz static frequency converter designed to the stringent requirements of the aerospace and defence industries.

Price Guide (Inc GST): POA

The GPCU combines advanced microprocessor-based monitoring, control and self-test diagnostic facilities with Thycon’s proven power control technology to provide a very reliable, high performance unit adaptable to a range of ground power requirements.

The GPCU consists of a static frequency converter which produces 400Hz power at up to 1000 volts. The high voltage power is transmitted to step-down transformers located at each distribution point where the power is transformed to 115/200 volts.

High voltage transmission eliminates the need for expensive regulators at each outlet and reduces power losses. Thycon GPCU systems are available with power ratings of 200, 300, and 400kVA. GPCU units can be easily paralleled to achieve higher power capacity or redundancy, as required.

Power is only drawn while the equipment is in use. After running on no load for a preset length of time, the equipment will automatically shut down. This feature, combined with high equipment efficiency, makes Thycon GPCU installations very cost effective.
