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.
