Title:
ELECTRIC POWER CONVERSION SYSTEM
Document Type and Number:
Japanese Patent JP2017147851
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric power conversion system capable of detecting imbalance of an output current in each electric power supply without using communication equipment.SOLUTION: Each of a master 10 and a slave 20 comprises: a switching circuit including a switch S1, a switch S2, and a main reactor L1; auxiliary resonance circuits 150 and 250 having a switch S3 and an auxiliary reactor L2; and a voltage detection part 51 that detects an inter-terminal voltage of the switch S1 or the switch S2. The master 10 comprises a controller 16 that generates a control signal GsA of the switch S3A on the basis of rising waveform or falling waveform of the inter-terminal electrode of the switches S1A and S2A. The slave 20 comprises a controller 26 that the control signal GsB of the switch S3B is equalized to the control signal GsA. The controller 16 or 26 observes a difference of the rising waveform or falling waveform in the master 10 and the slave 20, and detects imbalance of an output current.SELECTED DRAWING: Figure 2
