| Summary: | This paper presents a new hysteresis current controller concept for a three-phase grid-connected
inverter with reduced losses. This concept combines the advantages of single-band hysteresis
current control techniques and discontinuous PWM which satisfies pulse polarity consistency rule,
therefore reduces switching frequency over the same level of harmonic content. To further reduce
the switching losses due to the redundant phase, one phase of the inverter is clamped for a duration
of one third of the fundamental output period. Analytical model of this newly proposed controller
has also been derived. Simulation results are presented to show the effectiveness of the proposed
controller. |
