Power Supply
Diode
Cathode
FWD bias
Current flows
0.7V
Anode
REV bias
Blocks current
...source??
No Bias
Zener Diode
Voltage Regulator
Parallel with RL
Maintains constant voltage
Iz ..max ... IZ min ...
must be Reverse Bias
PZ nom = 1Watt
Measuring Instruments
Voltmeter AC = Eeff
Voltmeter on DC = E avg
Oscilloscope ... Epeak ... also Time/Freq
Capacitor
Increase the AVG
Ripple
Increase the Minimum
Bridge Rectifier
4 Diodes
Top and Bottom is AC source
Converts AC to DC
Sides produces DC
RS Resistor
Supply current to IL and IZ
Wattage 1/2W - 1W
Regulates the current in circuit
