Match List-I (Type of Inverter circuits) with List-II (Applications/Limitations) and select the correct answer using the codes given below the lists:
A. Adjustable voltage inverter
B. Pulse width modulated inverter
C. Current source inverter
D. Voltage source inverter
1. Limited speed range of motor
2. Capable of regeneration
3. Good input power factor at al! frequencies
4. Possibility of short circuit across the source
Detailed Solution for Test: Inverters- 2 - Question 1
• By using adjustable voltage inverter, speed range of motor is limited because of motor cogging at 6 Hz and below.
• In pulse width modulated inverter, input p.f. is good at all frequencies.
• A CSI has the capability of regeneration back to the a.c. line because d.c. link polarity can be reversed.
• In VSI, the misfiring of switching devices may cause short circuit across the source and create serious problems.
In current source inverters load voltage waveform V0 and load current waveform i0 respectively
Detailed Solution for Test: Inverters- 2 - Question 2
In a CSI, load current rather than load voltage is controlled, and the inverter output voltage is dependent upon the load impedance and the output voltage waveform. The load current and hence its waveform is independent of load impedance due to which a CSI has inherent protection against short-circuit across its terminals.
A single phase IGBT bridge inverter, compared to a single pulse PWM control, multiple pulse PWM
Detailed Solution for Test: Inverters- 2 - Question 3
In case of singte-putse width modulation (PWM), the width of the pulse is adjusted to reduce the harmonic. However, a single phase IGBT bridge inverter produces a square wave. This square wave contains harmonic, harmonic andharmonic.
If for a single-phase half-bridge inverter, the amplitude of output voltage is V0 and the output power is P, then their corresponding values for a single-phase full-bridge inverter would be respectively
Detailed Solution for Test: Inverters- 2 - Question 5
A single-phase full bridge inverter can operate in load-commutation mode in case load consists of
Detailed Solution for Test: Inverters- 2 - Question 6
In a 1-φ full bridge inverter if RLC load is underdamped, then the two thyristors (namely T1 and T2) shown in figure will get commutated naturally and therefore no commutation circuitry will be needed. Thus, load commutation will be possible.
Assertion (A): The terminal voltage of a voltage source inverter remains substantially constant with variations in load.
Reason (R): Any short-circuit across the terminals of a voltage source inverter causes current to rise very fast.
Detailed Solution for Test: Inverters- 2 - Question 8
A voltage source inverter is one in which the d.c. source has small or negligible impedance. Due to low internal impedance, the terminal voltage of a VSI remains substantially constant with variations in load. Reason is also a correct -statement because due to low time constant of internal impedance any short-circuit across the terminals of a VSI causes current to rise very fast. Hence, both assertion and reason are true but reason is not the correct explanation of assertion.
Assertion (A): The lower order harmonics are reduced by using some technique while the higher order harmonics are reduced by using filter.
Reason (R): The cost of the filter is reduced and at the same time transient response is also improved to a great extent.
