Title:
POWER CONVERTER AND RANKINE CYCLE SYSTEM
Document Type and Number:
Japanese Patent JP2019054625
Kind Code:
A
Abstract:
To simultaneously reduce a leakage current in a load connected to a multilevel inverter circuit on a main machine side and a leakage current in a load connected to an inverter circuit on an auxiliary machine side.SOLUTION: A power converter includes: a converter circuit 3 for generating an intermediate voltage; a multilevel inverter circuit 2 controlled in three levels; an inverter circuit 4 into which the intermediate voltage is input for driving; a controller 5 for controlling the multilevel inverter circuit 2 and the inverter circuit 4, and, at the same time, controlling the converter circuit 3 so that the intermediate voltage is maintained at a preset voltage. The generated intermediate voltage is used for an intermediate voltage of the multilevel inverter circuit 2 and an input voltage of the inverter circuit 4 together. Therefore, leakage currents in the load connected to the multilevel inverter circuit 2 and the load connected to the inverter circuit 4 are simultaneously suppressed.SELECTED DRAWING: Figure 1
