1. There is a full bridge inverter connected to a RL load. The DC source voltage is 100 V, R
= 20Ω, L = 50 mH and frequency of the output voltage is 60 Hz. Determine,
I.
an expression for load current
II.
power absorbed by the load
III.
average current in the DC source
IV.
amplitudes of the Fourier series components of the load voltage
V.
amplitudes of the Fourier series components of the load current
VI.
power absorbed by the load
VII.
total harmonic distortion of the load voltage and the load current for the
square-wave inverter
