Abstract
A power system includes at least one power unit, and each power unit has a direct current power source comprising at least two photovoltaic modules connected in series, each module having a positive and a negative output terminal, and a distributed inverter consisting of and an associated transistor switches connected to either the positive or negative output terminal of the at least two photovoltaic modules, and an alternating current power output. A power system has at least two power units, and each power unit has a direct current power source of at least one photovoltaic modules, and at least two transistor switches, wherein each power unit produces one polarity of voltage, used for generating alternating current power.
