Title:
DEVICE AND METHOD FOR SOC BALANCE CONTROL FOR DELTA STRUCTURE SEMICONDUCTOR TRANSFORMER-BASED ENERGY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/108429
Kind Code:
A1
Abstract:
The present invention relates to a device and method for SoC balance control for a delta structure semiconductor transformer-based energy storage device, for effectively operating a charging and discharging time of a system by controlling balance of battery SoC of a PCS connected by a delta connection so as to prevent overdischarging and overcharging of a specific battery, controlling a zero-phase-sequence component of the delta connection so as to balance the battery SoC for each phase, and controlling balance of an individual battery SoC. The device for SoC balance control for a delta structure semiconductor transformer-based energy storage device of the present invention is composed of an SoC balance control device that controls charging and discharging of a battery such that, in a PCS that performs charging and discharging from three-phase AC power, an A-phase PCS, a B-phase PCS, and a C-phase PCS connected by a delta connection, and the battery SoC of the PCS, are balanced.
