This paper presents an improved direct torque controlled reluctance synchronous motor drive for field-weakening applications. The contribution of this paper is twofold. First, a modified direct torque control (DTC) algorithm is proposed to enable a constant switching frequency, reducing the torque ripples significantly while simultaneously retaining the(More)
The reliability of micro inverters is an important factor as it would be necessary to reduce cost and maintenance of the small and medium scale distributed PV power conversion systems. Electrolytic capacitors and active power decouple circuits can be avoided in micro inverters with the use of a medium voltage DC-link. Such a DC-link based micro inverter is(More)
