Digital Electronic Control Unit (ECU)
The digital ECU for the Electric Starter Generator integrates a control board, an inverter board and a unidirectional HVDC-LVDC converter board in one housing. The ECU is designed for starting on a bus voltage of 270VDC, but can be reconfigured to work with an 115VAC/400Hz bus.
The ECU includes a novel fault detection algorithm which instantaneously detects potential faults in the machine. Its rated performance is in starting mode 20kW/270VDC and in generator mode 12kW/28VDC. The ECU weighs approximately 14 kg.
