“…State of the art solutions reduce the output voltage THD by means of either multi-loop strategies ([4]- [6]) or active filtering ([8]- [10]). However neither multi-loop strategies nor active filtering are applicable to the case of an ARPS due to stability constraints or unaffordable increase of cost, size and complexity, respectively [11].…”

AC power supplies generated by means of an inverter are under very restrictive specifications regarding their AC output voltage THD, even when they are supplying both linear and nonlinear loads. The presence of the low frequency harmonic content due to nonlinear loads operation, greatly increase the THD of the AC power supply output voltage.Traditional state of the art techniques approach this problem from two main sides: filtering and fast control loops. However, the proposed technique aims to solve the aforementioned problem from a different point of view: the inverter modulation technique. Therefore, the Harmonic Cancellation Technique (HCT) has been developed. It is a modulation technique which is able to cancel out the low frequency harmonics due to the nonlinear load operation through the proper pre-distortion of the inverter output voltage.The present paper presents the limitations of the available solutions space for the proposed modulation technique. It also provides an insight of the converter design parameters which may help to enlarge the ranges of operating conditions for which HCT can be applied.

Solid‐oxide fuel cell (SOFC) units normally supply power to the local load centers but the excess power can also be exported to the regional power grid, adding to the capacity and stability of the overall grid system. A SOFC power plant is equipped with a pulse width modulation (PWM) inverter. This paper presents the design of a new fuzzy logic regulator for a three‐phase inverter, using the strategy of an inverter flux vector control method. Criteria for designing the fuzzy controller are given and a comparison with the hysteresis method is presented. The flux vector approach is to generate the command pulses for low ripple current and constant switching frequency.
