    1. Winter Quarter Lab 3 P. 1 Title of the Lecture Application Of The Electrical Diodes

    2. AC vs. DC signals. Diode. Half & full bridge rectifiers DC power supply. Contents Instructor: In this lab, we will learn about electric circuit components and see some new basic electrical symbols. We will talk more about AC and DC signals, and learn about period, frequency, and Root-mean-squared voltage. We will also talk about Ohm’s law, series and parallel electrical connections, capacitors, measuring devices, diodes, and the components of a DC power supply.Instructor: In this lab, we will learn about electric circuit components and see some new basic electrical symbols.

Winter Quarter Lab 3 P. 3 DC vs. AC Signals Instructor: A direct current signal, shown above, has a constant current over time, while the alternating current signal below alternates sinusoidally with a steady frequency over time.Instructor: A direct current signal, shown above, has a constant current over time, while the alternating current signal below alternates sinusoidally with a steady frequency over time.

    4. Winter Quarter Lab 3 P. 4 Diode Instructor: Diodes allow current to only flow in one direction. There are two types of materials, p-type and n-type in a diode, and when the voltage is higher in the p-type material than the n-type material, it is forward biased and current is allowed to flow across the junction between the two types of materials.Instructor: Diodes allow current to only flow in one direction.

    5. Winter Quarter Lab 3 P. 5 Diodes: Reverse Biased Instructor: When the voltage is higher across the n-type material than the p-type material, the diode is reversed biased and no current can flow across the junction between the two types of materials, turning the device “off”.Instructor: When the voltage is higher across the n-type material than the p-type material, the diode is reversed biased and no current can flow across the junction between the two types of materials, turning the device “off”.

    7. Half Bridge Rectifiers Winter Quarter Lab 3 P. 7 Instructor: I half bridge rectifier makes use of the diode to cancel out the “negative” part of an AC source. In the plots shown, the diode turns off when the negative part of the sinusoid goes to the input, creating an output voltage of zero instead. It allows the positive part of the sinusoid to pass, however.Instructor: I half bridge rectifier makes use of the diode to cancel out the “negative” part of an AC source.

    8. Full Bridge Rectifiers Winter Quarter Lab 3 P. 8 Instructor: A full bridge rectifier makes use of two diodes, so that the current flows to the output in only one direction. Instead of just filtering out the negative voltage, this inverts the negative part of the signal, as shown on the bottom left plot. A capacitor is added to the circuit to smooth out the output. This is shown on the bottom right.Instructor: A full bridge rectifier makes use of two diodes, so that the current flows to the output in only one direction.

    9. DC Power Supply Winter Quarter Lab 3 P. 9 Instructor: This is a diagram of the full DC power supply that will be built in class today. The parts discussed are integrated to turn the household AC source into a constant DC output voltage. A voltage regulator is attached to the output to further smooth out the signal and supply a constant 5 volts.Instructor: This is a diagram of the full DC power supply that will be built in class today.
