A vector control technique for medium-voltage multilevel inverters
IEEE Transactions on Industrial Electronics, 2002 This paper presents a switching strategy for multilevel cascade inverters, based on the space-vector theory. The proposed switching strategy generates a voltage vector with very low harmonic distortion and reduced switching frequency. This new control method is an attractive alternative to the classic multilevel pulsewidth modulation techniques ...

The Absolute Voltage and the Lead Vector of Wilson's Central Terminal.
Japanese Heart Journal, 1996 The absolute potential value of Wilson's central terminal was calculated at 2 msec intervals during a cardiac cycle in 60 clinical cases. Starting from the body surface potential data at 128 thoracic locations, the effect of immersion of the body into an infinite conductor on the surface potential was calculated to obtain values with reference to zero ...
