Today i tested a Converter 3x400V > 1 x 240V 40A 50/60Hz. Test with 2000W 230V Induktive cooking unit: 240V Output Sinus Wave, better than the inlet from Grid. The Inductive Unit is a perfect Load with sinusoidal Curent. Test with Mitsubishi IMiev: External Charger 10A, 11 % THDI, perfect. Test with Smart Electric Drive, (Tesla-tecnology) does not accept this Sorce. Test with Teslarodster with 10A 240V Cable: the same, Grid Synch Fault. Test with ACPropulsion 110-240V 10-80A >Input 3x15A 400V, Output excellent up to this Converter Limit 40A 240V The Output Voltage is throgh PEM related with the 3phase Input, with Starpoint conected to earth, The Output has a symetric Voltage about 140V to Earth. Has sombody an idea what is the nogo criteria. The Transformer in Teslomotors Shop/Service Zürich, was floting secondary Voltage and charged after conecting one secondary Side to earth, but i canot do that, becaus the Converter Output is nonisolatet. Next step is find an Nissan Leaf to test. Secand next, trie with an AC Propulsion Charger 240V 80A, should be the same like Teslas. Dezember 2009 i had a conference call with the engineering manager charging systems , and European responsible peaple for Tecnics, I could ask them for support.
