I HAVE THE POWER!!!!...... supplies
This section of a PS can lower OR increase the AC supply voltage. It also provides isolation from AC to DC components.
Xformer
Capacitors impede this type of signal
LOW
This component in power supplies stores energy in an Electromagnetic field
Inductors
A shorted diode will result in this reading on an Ohmmeter regardless of biasing
Low ohms
This testing instrument displays RMS values
Multimeter
This section of a PS smooths out pulsating DC
Filter
How a "choke" coil would be terminated in relation to the output of a DC power supply
Series
This component protects from high powered, low frequency's voltage surges
MOV
This device will give two different readings in working condition depending on its biasing.
Zener
This circuit contains 6 diodes
3 phase bridge rectifier
This PS section allows for the output voltage to remain constant over many scenarios
Regulator
DAILY DOUBLE!!!!!!
This rating of a capacitor is what determines how well it filters an input signal
Capacitance
This component protects power supplies from short circuit conditions. Typically one time use
Fuses
Open on rectifier
Voltage divider
This section can either take a DC voltage and increase it many times over OR provide many different voltage taps at the output.
Multiplier/Divider
Inductors oppose a change in this electrical property.
Current
A type of power supply that has its rectifier tied directly to filtering
Unregulated
CAUTION! You must do this before working on any power supply even if it is disconnected from power.
discharge capacitors
As this increases the amount of filtering required to produce pure DC also increases
load or current draw
This section can be configured in such a way that it has a output that can be calculated by using the formula Vpeak x 0.638 = Vavg
Rectifier
This is the voltage that capacitors charge too. Be careful! Don't exceed this limit! Unless you want the smoke
Peak voltage
This is how we refer to a negative voltage in relation to a 0 potential point.
Below ground
The output of a bridge rectifier if two adjacent diodes have failed open
0v
The device and failure that would cause of a low DC output. Assume the input in sufficient.
