Clinical implications are that health professionals can focus their attention on the variables most likely to(More)

This paper presents a three-phase cascaded H-bridge converter for a stand-alone photovoltaic (PV) application. The multilevel topology consists of several H-bridge cells connected in series, each one connected to a string of PV modules. The adopted control scheme permits the independent control of each dc-link voltage, enabling, in this way, the tracking of(More)
