Abstract
A power converter of the present invention is configured to convert DC power generated by a power generator () into AC power. The power converter includes: a boost converter circuit () configured to boost an output voltage of the power generator (); an inverter circuit () configured to convert an output voltage of the boost converter circuit () into AC power and to interconnect the AC power with a power system (); a buck converter circuit () configured to perform power conversion of output power of the boost converter circuit () and to supply resultant power to an internal load (); and a controller (). The controller () is configured to control the output voltage of the boost converter circuit () to be lower than or equal to a second voltage value which is less than the maximum value of AC voltage of the power system (), in a case of supplying output power of the power generator () to the internal load () via the boost converter circuit () and the buck converter circuit ().
