摘要：In a multilevel power conversion circuit, output harmonic waves and

electromagnetic noise can be reduced as the number of output levels is increased. This,

however, increases the number of elements constituting the circuit, causing the degree ofdifficulty in mounting to increase, cost to increase, and reliability to decrease. It is

necessary to provide a circuit configuration, a design method, and a mounting method forobtaining, at low cost, a multilevel power conversion circuit using a large number ofelements. A power conversion circuit is used as a unit module and is equipped with inputand output terminals each mounted on the main circuit in an open state, wherein theinput and output terminals have a mechanism by which the input and output terminalscan be flexibly interconnected with the input and output terminals of another samemodule. A plurality of the highly expandable power conversion circuit modules are usedand combined using various connection methods to obtain multilevel power conversioncircuits having various configurations. This makes it possible to change power conversioncircuit performances and characteristics, such as the number of levels, voltage, current,power, the number of phases, etc., only by reconfiguring the modules and to provide amultilevel power conversion circuit most suitable for various applications at low cost.
