In this paper a new induction motor speed method based on Chirp-Z Transform and zero padding of the supply current is presented. The algorithm has been implemented on a microprocessor. A virtual instrument has been built to control and to monitor on line motor speed. The motor speed method has been tested on a 7.5 kW induction motor driven by a pulse width(More)

Ghetti STMicroelectronics, Central R&D Via Olivetti 2, 20041 Agrate Brianza (Italy) Introduction While device dimensions are scaled down the shallow trench isolation (STI) technology could face with reliability problems related to the impact on(More)
− In recent years the problem of harmonic pollution has become more urgent, because of the development in distribution systems of non linear loads that draw non-sinusoidal currents. This paper presents a time domain method for harmonics sources detection in power systems, which can be usefully applied also in presence of unbalance or asymmetry. Harmonic(More)
