Yes
No
Characteristic of a single -phase full wave rectifier are
Higher average output voltage
higher efficiency
high speed
reduced ripple factor
Types of rectifier including
Single phase half wave rectifier
Single phase full wave rectifier
three-phase rectifier
all of the above
An uncontrolled rectifier uses a diode as a switch while a controlled rectifier uses an SCR as a switch
True
False
The Existence of an inductor in series with the load resistance will INCREASE the average output voltage.
True
False
The addition of a freewheeling diode parallel with an RL load will prevent the negative output voltage waveform from going negative.
True
False
The addition of a freewheeling diode parallel with an RL load will increase the average output voltage as well as the average output current.
True
False
Single phase rectifier are used in
Low power application
High power application

Three phase rectifier provides some advantages over a single phase rectifier such as
Low average output voltage and higher ripple frequency
higher average output voltage and higher ripple frequency
higher average output voltage and low ripple frequency
Low average output voltage and Low ripple frequency
Three phase rectifiers are suitable for high-power applications exceeding 5 kW.
True
False
