Patent ID: 11960250
Assignee: MITSUBISHI ELECTRIC CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. An electric power conversion apparatus comprising:
a main circuit including a switching element, the main circuit to convert electric power input to the main circuit and supply a result of the conversion to a load;
a detector to detect an output value of the main circuit; and
a controller to control the main circuit, wherein
the output value of the main circuit is an output voltage of the main circuit or an output current of the main circuit,
the controller switches a control scheme of the main circuit from a first control scheme to a second control scheme at a first time point when the output value starts to vary,
the controller predicts, on the basis of a detection value of the detector, a prediction value of the output value of the main circuit, which is an output value of the main circuit at a future time point that will occur after the first time point,
the controller switches the control scheme of the main circuit from the second control scheme to the first control scheme at a second time point when a determination is made, based on the prediction value of the output value of the main circuit, that switching of a variation direction of the output value will occur, and
the first control scheme is feedback control under which the output value is controlled to follow a command value.
