Worksheet 24-Power Supplier Filters Flashcards
How is the waveform described that comes from a full wave rectifier?
The voltage waveform of a full-wave rectifier is called ripple voltage.
In what configuration to the load is a choke filter connected?
A choke inductor is connected in series to the output of the load.
How is the capacitor connected for it to be used as a signal filter?
For a capacitor to function as a filter, it must be placed in parallel to the output load.
What does a choke inductor do to the output of the rectifier?
The choke inductor resists change in current of the output under varying load conditions.
How does the capacitor maintain a higher average output signal?
When AC signal lowers to a level less than the voltage of the stored energy of the capacitor, voltage then comes from the capacitor to the load.
What is the configuration of a Pi filter?
A Pi filter contains two shunt capacitors and a choke inductor in series between them.
What is the purpose of a bleeder resistor placed at the output?
A bleeder resistor is also called a safety resistor that drains the capacitor when the load is removed.
