Full- and Half-Wave Rectifier Operation Flashcards
The rectifier output is ______ that has a ripple frequency.
The rectifier output is pulsating DC that has a ripple frequency.
This is a typical ______ rectifier circuit.
This is a typical half-wave rectifier circuit.
What are the functions of T1, D1, and RL?
T1 - The transformer is in the input section and steps up or steps down the AC voltage.
D1 performs the rectification.
RL is the load resistor that develops the output signal.
What determines when D1 conducts current?
When the AC input voltage is positive, D1 is forward biased and conducts. The current flow develops a signal across RL, producing an output.
When the AC input voltage is negative, D1 is reverse biased and does not conduct. No output signal is developed.
A continuous input produces a series of pulses with a frequency that is the same as the ________.
A continuous input produces a series of pulses with a frequency that is the same as the input frequency.
To check for normal operation, measure the DC output voltage with a multimeter and compare to the _____. Since transformers can step up or step down voltage, the DC output voltage is calculated using the voltage on the ________.
To check for normal operation, measure the DC output voltage with a multimeter and compare to the calculated DC output voltage. Since transformers can step up or step down voltage, the DC output voltage is calculated using the voltage on the secondary coil.
What formula is used if this half-wave rectifier produces 19 VDC?
If the input voltage is given as an RMS value, you must convert the voltage to peak using what formula?
Vp = Vrms ÷ 0.707
This is a typical ______ rectifier circuit.
This is a typical full-wave rectifier circuit.
Applying AC to the primary of T1 produces two AC signals on the secondary. They are 180 degrees out of phase. When the AC input voltage is positive, which of the two rectifiers conduct?
When the AC input voltage is positive, D1 is forward biased and conducts. D2 is reverse biased and does not conduct.
When the AC input voltage is negative, D1 is reverse biased and does not conduct. D2 is forward biased and conducts.
The current flow from D1 and D2 develops a signal across RL, producing an output. A continuous input produces a series of pulses with a frequency that is ______ the input frequency.
The current flow from D1 and D2 develops a signal across RL, producing an output. A continuous input produces a series of pulses with a frequency that is twice the input frequency.
