A simple rectifier is a diode. It only has two terminals and will only allow electron flow in one direction only. A controlled rectifier (SCR=silicon controlled rectifier) has a third connection (gate). Which as the name suggests, is a gate that controls at which point the rectifier will work. It therefore has a level of control.
There are various types and you would need the application specification, to get the best use of them.

Difference between silicon-controlled rectifier and diode?
silicon controlled rectifier is a 3 terminal 4 layer device which has 2 consecutive P N junctions here the three terminals called anode, cathode and gate gate controls the conduction of the scr but diode just conducts in forward bias and blocks in reverse bias
What is the difFerence between nc and cnc?
NC is numerically controlled (hard wired) and CNC is computer numerically controlled.
What is the difference between a half wave rectifier and a negative clipper?
As far as general principles apply, they both perform the same function: using a diode.
What is the difference between a one diode rectifier and a two diode rectifier?
A one diode rectifier is called a half wave rectifier and only allows current flow for the positive portion of the sine wave. A two diode rectifier, or full wave rectifier allows positive current flow during the positive portion of the wave as well as positive current flow during the negative portion of the sine wave. This results in a much cleaner DC power signal. The addition of a capacitor in the output circuit will clean up the signal very nicely.
What is the basic difference between a full wave bridge rectifier and a full wave center tapped rectifier?
A full-wave bridge rectifier with 4 diodes gives a dc output voltage equal to the average voltage of the whole transformer secondary. A FW rectifier with 2 diodes and a centre-tapped secondary gives an output voltage equal to the average voltage of half the secondary. If you have a 12-0-12 transformer, the bridge gives a 24 v output, while the 2-diode FW rectifier gives 12 v (approximately).

What is the difference between uncontrolled response and controlled response?
An uncontrolled response is a natural response to an unconditioned stimulus or stimuli. A controlled response is a response taught to said person by pairing it with a formally neutral stimulus which now turns into the controlled stimulus.
What is the difference between a controlled experiment and observation?
all it is is the uncontrolled experiment is a little bit different
What are the different between uncontrolled and controlled rectifier half wave?
uncontrolled wave rectification is achieved using a single diode in a one phase supply, or by using three diodes in a three phase supply. In uncontrolled wave rectification, either the positive or negative half of the AC wave is passed or the other half is blocked. Since only one half of the input waveform reaches the output, it is very incompetent if used for power transfer. A controlled wave rectifier uses a thyristor instead of a diode, therefore the firing angle can be adjusted with a gate pulse.
What is Difference between uncontrolled events and controlled events?
a controlled event is a variable that you can manipulate and change or do anything you want with you want. uncontrolled event is something you cannot help. in example, if you were doing something with eye colors, you just have to deal with the eye color the person has. you cannot change it.
What is the difference between controlled and uncontrolled observations?
Controlled observations involve manipulating variables and controlling conditions to observe specific effects, while uncontrolled observations involve observing natural events as they occur without intervention. Controlled observations are often used in experiments to test hypotheses, while uncontrolled observations are more common in naturalistic studies where researchers aim to understand behaviors in their natural context.
What is the difference between controlled redundancy and uncontrolled redundancy?
Controlled redundancy refers to intentionally duplicating certain components in a system to ensure reliability and fault tolerance, whereas uncontrolled redundancy occurs unintentionally due to inefficient processes or lack of coordination. Controlled redundancy is planned and managed to enhance system performance, while uncontrolled redundancy can lead to inefficiencies and waste of resources.
What is the difference between a controlled and an uncontrolled?
A controlled experiment involves the manipulation of one or more variables while keeping others constant to observe the effects of those changes, allowing for a clear cause-and-effect relationship. In contrast, an uncontrolled experiment lacks this level of control, making it difficult to isolate the effects of specific variables, which can lead to confounding results. Controlled experiments are more reliable for drawing conclusions, while uncontrolled experiments may provide preliminary insights but require further investigation.
Uncontrolled muscle contractions the same as skeletal muscle contractions?
Uhh, no uncontrolled muscle contraction occurs in smooth and cardiac muscles... there are many differences between these two types of muscles; controlled and uncontrolled muscle contraction.....
What is the difference between a controlled and uncontrolled railroad crossing?
A controlled railroad crossing features signals, gates, or other warning devices that alert drivers and pedestrians to the approach of a train, enhancing safety at the intersection. In contrast, an uncontrolled railroad crossing lacks these safety measures, relying instead on signage to indicate the presence of the tracks, which can pose a higher risk for accidents. Drivers and pedestrians at uncontrolled crossings must be more vigilant and aware of their surroundings when crossing the tracks.
What are Similarities between controlled and uncontrolled rectifiers?
Both controlled and uncontrolled rectifiers convert alternating current (AC) to direct current (DC). They share similar circuit configurations, often utilizing diodes or thyristors for the conversion process. Additionally, both types are used in various applications, such as power supplies and motor drives. However, the key difference lies in the ability of controlled rectifiers to regulate output voltage and current through control signals, whereas uncontrolled rectifiers provide a fixed output based solely on the input AC waveform.
What is the difference between a fully controlled and a semi controlled converter?
Fully controlled rectifier uses only SCR's Negative output voltages are obtained two quadrant control wide range control costly semi converter uses diodes and SCR's only positive output voltages are obtained one quadrant control only positive half cycles are controlled
