What component converts AC power to DC in the MQ-9?

The correct choice in this context is the Direct Current Power Supply (DCPS). The DCPS is a crucial component in the MQ-9 systems as it specifically takes in alternating current (AC) and converts it to direct current (DC), which is necessary for the operation of various electronic systems and onboard equipment that require stable and reliable DC power.

The MQ-9’s systems rely on DC power for functionality, and the DCPS ensures that the electrical power supplied meets the necessary specifications for these systems. This conversion process is essential, as many components require DC to operate effectively, and the DCPS plays a pivotal role in supplying that power.

Understanding the role of the DCPS clarifies why it is responsible for converting AC to DC, which is a fundamental function in aircraft electrical systems. Other components mentioned, while part of the broader electrical system, serve different functions and do not perform this specific conversion.
