engineering recuitment GATE EE 2023-24 Test Series Power Electronics and Drives Inverters Single Phase Voltage Source Inverters
Using frequency domain analysis estimate the ratio of 5th and 7th harmonic currents in a purely inductive load that is connected to the output of a single-phase half bridge inverter with square wave pole voltages.
1
5th harmonic current will be nearly double of the 7th harmonic current
2
5th harmonic current will be 40% more than the 7th harmonic current
3
5th harmonic current will be zero while 7th harmonic current will be present
4
Both 5th and 7th harmonic currents will be zero
