8-D-37: Display System Power Supplies

8-37D1: The display power supply provides the following:

5 volts DC for logic circuits and ± 12 volts DC for analog and sweep circuits.

+18 volts DC for the pulse forming network.

80 volts AC for the antenna resolver circuits.

All of the above



8-37D2: The display power supply provides the following:

All of the above

5 volts DC for logic circuits.

± 12 volts DC for analog and sweep circuits.

17kV DC for the CRT HV anode.



8-37D3: In a display system power supply what is the purpose of the chopper?

It acts as an electronic switch between the raw DC output and the inverter.

It interrupts the AC supply line at a varying rate depending on the load demands.

It regulates the 5 volt DC output.

It pre-regulates the AC input.



8-37D4: In a display system power supply, what is the purpose of the inverter?

Produces the pulsed DC input voltage to the power transformer.

Inverts the polarity of the DC voltage applied to the voltage regulators.

Provides the dual polarity 12 volt DC supply.

Acts as the voltage regulator for the 5 volt DC supply.
