A400M Control Electronics
| PSAC | |
| System Overview | The Control Electronics Assembly (CE) provides the capability to control the EBHA pump motor in closed loop velocity mode. This is accomplished as a combination of hardware and software functions. The CE is provided velocity command and enables signals from the FCC, and outputs PWM command signals to the power electronics to control the three phase IGBT bridge and regulate current in the motor. The CE uses motor shaft position information from the motor resolver to determine motor velocity and commutate the motor. |
