INVERTER

What is the output of an inverter?

• DC

• AC

What are the good candidates for switches in dc to ac conversion techniques?

• Diode

• SCR

• MOSFET

• BJT

Why output of an inverter is not sinusoid?

• Because the frequency not same

• Voltage higher than input

• Because rich of harmonics component

What are the techniques to control the output voltage?

• PWM

• buck converter

• dc chopper

What analysis that can be used to represent the periodic waveform?

• Trigonometry analysis

• Fourier analysis

• Laplace transform

Why we have to do the Fourier analysis?

• To find total harmonic distortion

• To find output current

• To find rms output voltage

What is the fundamental value?

• The sine wave that has same frequency value with the original value

• The sine wave that has odd order frequency value with the original value

• The sine wave that has even order frequency value with the original value

What is the rms output voltage for the dual supply single phase inverter with RL load

• V_orms = V_s

• V_orms = 2V_s

• V_orms = V_s / 2

How many types of switching scheme in inverter?

• 1

• 2

• 3

• 4

What is the difference between square wave and quasi square wave waveform?

• the firing angle

• the extinction angle
