Title:
ELECTRIC POWER CONVERSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/140571
Kind Code:
A1
Abstract:
A main circuit (2) includes a switching element, and converts electric power inputted thereto, and supplies the resultant to a load (5).
A detection unit (6) detects an output value of the main circuit (2). The output value of the main circuit (2) is an output voltage of the main circuit (2) or an output current of the main circuit (2). A control device (3) controls the main circuit (2). At a first time point when the output value starts fluctuation, the control device (3) switches the control scheme of the main circuit (2) from a first control scheme to a second control scheme. At a second time point when it is determined, on the basis of the value detected by the detection unit (6), that switching of a fluctuation direction of the output value occurs, the control device (3) switches the control scheme of the main circuit (2) from the second control scheme to the first control scheme.
