Description

Technical Field

[0001] This utility model belongs to the field of bidirectional inverter technology, specifically a bidirectional inverter energy storage charging and discharging interactive device. Background Technology

[0002] A bidirectional inverter is a power electronic device capable of bidirectional conversion between direct current (DC) and alternating current (AC), primarily used in energy storage systems, renewable energy sources, and electric vehicles. As a power electronic conversion device, a bidirectional inverter possesses bidirectional energy flow capability, with its core functions being inversion and rectification. In inversion mode, DC power is modulated and filtered by a high-frequency switch to output AC power, meeting the grid voltage and frequency requirements. In rectification mode, AC power is converted to DC power by a converter, filtered, and then stored in batteries or other DC devices. Bidirectional inverters are mainly used in energy storage systems (ESS), electric vehicles (EVs), microgrids, and UPS systems. In existing technologies, the conventional assembly structure of bidirectional inverters is not robust enough, resulting in poor overall stability; moreover, the lack of support points on its outer surface makes installation and fixing to external load-bearing structures cumbersome and inconvenient.
