1. SINTEF Energy Research 1 Proposed Pressure Tolerant Converter Demo Located on an existing subsea field At 1000-3000 m sea depth Operated and monitored from existing infrastructure In a pressure compensated vessel Operating power: 100-200kW Supplied power: 5-20kW

2. SINTEF Energy Research 2 Demo Power Circuit and Control Pressure tolerant power circuit Simple, pressure tolerant control and monitoring circuit

3. SINTEF Energy Research 3 Proposed Demo in Pressure Vessel Before or in parallel to subsea installation, the Demo can be subject to long-term test in a 70 liter 300 bar pressure vessel Pressure vessel planned for the SINTEF subsea laboratory The pressure vessel will accommodate the complete demo comprising two phase-legs
