Satellite communications systems, methods, and related devices are described. The first converter includes a unit for controlling active power and a unit for controlling reactive power and the second converter includes a unit for controlling a voltage of a DC system and reactive power or AC voltage of a power system. In an alternate embodiment the generated trace may be throttled to ensure the available bandwidth is not exceeded. The monitor circuit may be configured to detect the requested voltage change and to provide an indication that the voltage change is complete. On the way, the data may be encrypted, andor a data integrity signature calculated.
