Exam 4: Diode Circuits

When using a capacitor-input filter,the initial rush of current when the power is turned on is called the ripple current.

The capacitor-input filter produces a dc output voltage equal to the peak value of the rectified voltage.

It is extremely rare that equipment failure is caused by troubles in the power supply.

The plus sign on a filter capacitor indicates that it is

More often than not,equipment failure is caused by

A clamper circuit adds

A device inserted between the bridge rectifier and capacitor-input filter that is used to prevent an onrush of current is called

What is the circuit shown in Figure 4-8 (a)?

A diode circuit used to protect a sensitive circuit is called a ________.

Most power supplies use a slow-blow fuse that can temporarily withstand overloads in current.

Half-wave rectifier voltage produces

In electronic equipment power supplies,the transformer steps the line voltage down to lower levels that can more easily be used with semiconductor devices.

What is the circuit inside electronics equipment that converts the ac input voltage to an almost perfect dc output voltage?

For low-voltage power supplies,the LC filter has been replaced by an integrated circuit.

A circuit that removes all the positive parts of the input signal is a

The half-wave rectifier has a diode in series with a load resistor.

What is the small ac load voltage that can be measured (with an oscilloscope)at the output of a choke-input filter?

The bridge rectifier is similar to a full-wave rectifier because it produces a full-wave output voltage.

The choke-input filter is seldom used in recent years because of its cost,bulk,and weight.

A clipper is a circuit that removes either positive or negative parts of a waveform.
