Six-Step Three-Phase Inverter
For the six-step three-phase inverter of Fig. 8-28a, the dc input is 100 V and the fundamental
output frequency is 60 Hz. The load is wye-connected with each phase of the load
a series RL connection with R 10 and L 20 mH. Determine the total harmonic distortion
of the load current.
■ Solution
The amplitude of load current at each frequency is
