Abstract:
1. A DC-DC converter, comprising: a transformer; a voltage-source power converter that is provided at a primary side of the transformer; a first voltage detection circuit that detects a first voltage between first input and output terminals of the voltage-source power converter; a current-source power converter that is provided at a secondary side of the transformer; a second voltage detection circuit that detects a second voltage between second input and output terminals of the current-source power converter; a current detection circuit that detects an input-output current between the second input and output terminals of the current-source power converter; and a controller that controls the voltage-source power converter and the current-source power converter to transfer power between the primary side and the secondary side of the transformer, wherein the controller includes: the calculation unit performs the calculations based on one of the plurality of parameter sets that is selected from the table unit, and the controller controls the voltage-source power converter and the current-source power converter based on the command value.
