Methods and systems for operating a two-stage power converter

A power conversion system (14) for providing power to an electrical grid (22) is described. The system includes a boost converter (24) coupled to a photovoltaic (PV) array (12) and configured to control a PV array voltage. The system also includes an inverter (26) coupled to the boost converter by at least one conductor (36) and configured to regulate a voltage drop across the at least one conductor. The system also includes a system controller (16) configured to control operation of the boost converter and the inverter.
