Abstract: Unique systems, methods, techniques and apparatuses of an exciterless synchronous machine are disclosed. One exemplary embodiment is a salient pole rotor for an electric machine comprising one set of pole pairs including a first, second, and third pole pair; a field winding; a set of energy harvest windings, each winding mounted to each of the plurality of pole pairs and structured to receive a harmonic component of AC power from a stator; and a DC power supply structured to receive the harmonic component from the set of energy harvest windings, convert the harmonic component to DC power, and output the DC power to the field winding. The set of energy harvest windings are arranged in a first sequence on the first pole pair, a second sequence on the second pole pair, and a third sequence on the third pole pair, and each sequence is different.

Abstract: Unique systems, methods, techniques and apparatuses of a power converter are disclosed. One exemplary embodiment is an electrical power conversion system comprising a first converter stage, a second converter stage, a third converter stage, and a control system. The first converter stage is operable to boost DC power received from a DC power source. The second converter stage is operable to boost DC power received from the first converter stage. The third converter stage includes an inverter. The control system is structured to receive as input voltage (Vpv) and current (Ipv) output by the DC power source, voltage (Vdc) output by the second controller stage, and voltage (Vac) and a current (Iac) which are output by the third stage to an AC electrical power system, provide a control command for the first converter stage, and process the information of Vdc, Vac and Iac to provide control commands for the inverter switches.

Abstract: Methods, systems, and computer readable media for managing the distribution of photovoltaic power in a multi-floor building are disclosed. According to one aspect, a method includes determining power requirements for each of a plurality of loads associated with a respective plurality of floors in a multi-floor building, wherein each of the plurality of floors includes a direct current (DC) distribution bus. The method further includes using a PV converter to supply a power output from a PV source to one or more of the plurality of loads via one or more respective DC distribution buses, wherein the power output is supplied to the one or more of the plurality of loads in an order such that each subsequent load is supplied at least a remaining portion of the power output after the power requirements of a previously supplied load is fully satisfied.
