POWER CONVERTER, SOLAR ENERGY DEVICE AND SOLAR ENERGY POWER CONVERSION METHOD

摘要

A power converter includes a plurality of converters, a control device, and a signal adjustment device. The converters are connected to the photoelectric conversion cells respectively. The control device generates a base signal based on electrical power output from at least one type of photoelectric conversion cell out of plurality types of photoelectric conversion cells. The base signal is a signal that is a base for a plurality of control signals to control the converters individually so that electrical power output from the photoelectric conversion cells reaches a maximum power point of each of the photoelectric conversion cells. The signal adjustment device multiplies the base signal by a constant, and supplies a signal generated by the multiplication by the constant, as the control signal, to the converter which is a signal supply destination.

1. A power converter comprising:
a plurality of converters each of which is connected to each of a plurality types of photoelectric conversion cells which have sensitive wavelength bands differing from one another and has a function to convert electrical power output from the photoelectric conversion cell connected; a control device that, based on the output electrical power output from at least one type of photoelectric conversion cell among the plurality types of photoelectric conversion cells, generates a base signal from which a plurality of control signals are to be generated to control the plurality of converters individually so that electrical power output from the photoelectric conversion cell, which is a source of output of the output electrical power, reaches a maximum power point; and a signal adjustment device that multiplies the base signal by a constant and supplies a signal generated by the constant multiplication, as the control signal, to the converter which is a signal supply destination.
