A single-phase inverter is fed from a 100 V de source and is controlled using a quasi-square wave modulation scheme to produce an output waveform, v(t), as shown. The angle o is adjusted to entirely eliminate the 3^rd harmonic component from the output voltage. Under this condition, for v(t), the magnitude of the 5th harmonic component as a percentage of the magnitude of the fundamental component is _______ (rounded off to 2 decimal places).
