Bidirectional direct current-direct current converter, has controller including table unit that includes set of parameter sets, and calculation unit performing calculations based on of parameter sets that are selected from table unit

摘要

The converter has a current detection circuit detecting an input-output current between input and output terminals of a current-source power converter (2). A controller controls a voltage-source power converter (4) and the current-source power converter to transfer power between a primary side and secondary side of a transformer (3), where the controller includes a calculation unit to perform calculations based on voltage. A table unit includes a set of parameter sets, and a calculation unit performs the calculations based on the parameter sets that are selected from the table unit.
