Abstract: A photovoltaic power system includes module strings each having photovoltaic modules connected in series. The power system further includes a generator terminal box having DC converters. The power system further includes a generator main connection line and an AC inverter. Each module string is electrically connected to a respective one of the DC converters for the module string to provide a DC voltage generated by the photovoltaic modules of the module string to the respective DC converter. The DC converters output a combined DC voltage based on the DC voltages from the module strings to the AC inverter via the generator main connection line for the AC inverter to transform the combined DC voltage into an AC voltage. The generator terminal box and the AC converter are spatially separate from one another.

Abstract: A method of controlling a direct current (“DC”) chopper controller having a switch and a storage choke in which the choke has a current dependent on the switching of the switch on and off includes the following. A current variable derived from one of the time averaged value of the current of the choke and the peak value of the current of the choke is determined. A switching frequency for synchronizing the turning on and off the switch is calculated as a function of the current variable and on whether the current variable exceeds a current threshold. The switching frequency is determined to be a predetermined low frequency if the switching frequency is lower than the low frequency and is determined to be a predetermined high frequency if the switching frequency is greater than the high frequency. The switch is switched on and off in accordance with the switching frequency.
