Title:
ELECTRIC POWER CONVERSION APPARATUS
Document Type and Number:
Japanese Patent JP2015046985
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric power conversion apparatus capable of suppressing voltage fluctuation when a load is rapidly changed without using a sensor for detecting a load current and a capacitor of a large capacity for suppressing the voltage fluctuation.SOLUTION: An electric power conversion apparatus 10 includes: an electric power conversion circuit 11 which outputs an electric current corresponding to an electric current command value to thereby convert an input DC power or AC power into a constant DC power; a capacitor 12 connected to an output part of the electric power conversion circuit; and voltage control means 14 for outputting the electric current command value to the electric power conversion circuit in order to control the voltage of the capacitor to a set value. The voltage control means calculates the electric current command value from a process value Vand a set value Vof the voltage of the capacitor.
