Title:
ELECTRIC POWER CONVERSION SYSTEM
Document Type and Number:
Japanese Patent JP2017147852
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 10a and a slave 20 comprises: auxiliary resonance circuits 150 and 250 in which a switch S1, a switch S2, a main reactor L1, a switch S3, an auxiliary reactor L2, and a diode Ds are serially connected; a voltage detection part 51 that detects an inter-terminal voltage of the switch S1 or the switch S2; and control parts 16 and 26 that generate control signals GpA, GnA, GpB, and GnB of the switches S1 and S2, and generates control signals GsA and GsB of the switch S3 on the basis of rising waveform or falling waveform of the inter-terminal voltage of the switches S1 and S2. One of the master 10 and the slave 20 observes a difference of the control signals GsA and GsB, and detects imbalance of an output current of the master 10 and the slave 20.SELECTED DRAWING: Figure 2
