Abstract:
The performance of two 20-kHz actuator power systems being built for an advanced launch system are evaluated for a typical launch scenario using an end-to-end system simulation. Aspects of system performance ranging from the switching of the power electronic devices to the vehicle aerodynamics are represented in the simulation. It is shown that both systems adequately stabilize the vehicle against a wind gust during a launch. However, it is also shown that in both cases there are bus voltage and current fluctuations which make system power quality a concern.
