Power generation system for a dual-voltage

摘要

The three phase alternator stator coil is star wound having a neutral point (N) connected to a second sub-network operating at a lower voltage value (Ub) than a first voltage (Us) network. An electronic controller and voltage regulator (22) controls and regulates the energy transfer from one to the other of the sub-networks in a completely reversible way. The rectifier of the generation system includes a three phase wave shaper (21) having six transistor switches (H1 -H3; L1 - L3) mounted in series and in the same sense, by group , between earth and the voltage (Us), the highest for each of the three stator phases. each of the six transistors is driven by the electronic control units (22) which are designed to link the average value of the three phases to a set value for the voltage (Ub) as input to the second sub-network. The system has two filters, one (23) fitted in the neutral point (N) at the input to the low voltage sub-network (Ub) and one (24) at the output of the wave shaper and input to the high voltage sub-network (Us).
