1000A AC-DC Power Supply Ushering in a New Era of High-Efficiency Energy

The new generation 1000A AC-DC power supply employs full-bridge PWM modulation technology and a high-frequency switching architecture. Utilizing silicon carbide (SiC) power devices and adaptive zero-voltage switching (ZVS) technology, it reduces switching losses by 70%. Its input voltage range covers 220V-380V AC, with continuously adjustable output current from 1-1000A. Voltage accuracy reaches ±0.1%, featuring low ripple noise.

The Bangzhao BEG series achieves power scalability through modular design, delivering 400kW output per unit. Multiple units can be paralleled to support megawatt-level applications. Its built-in intelligent monitoring system, controllable via RS485/CAN, provides real-time monitoring of voltage, current, power, and other parameters. Multiple protection functions, including overvoltage, overcurrent, and short-circuit protection, ensure stable operation in environments ranging from -10°C to 50°C.

Application Scenarios: Comprehensive Coverage from Laboratory to Industrial Sites
1. Electric Vehicle Charging Network Upgrade
In the DC fast-charging domain, 1000A power supplies enable 800V high-voltage platform electric vehicles to achieve “5 minutes of charging for 200 kilometers of range.”

2. Precision Power Supply for Semiconductor Manufacturing
Semiconductor equipment demands exceptional power stability. This power supply delivers adjustable DC voltage (50-1000V) with less than 0.05% fluctuation for ion implanters, etchers, and other critical devices, ensuring nanometer-level process precision.

3. Aerospace High-Voltage Testing
During satellite power system testing, it withstands temperature variations from -40°C to 85°C and intense electromagnetic interference, delivering stable energy to electric propulsion systems.

4. Bidirectional Charging/Discharging for Energy Storage Systems
The regenerative electronic load enables dual-mode operation as either a power source or load. During power conversion system (PCS) testing, it recycles 98% of electrical energy back to the grid, saving over 200,000 yuan in annual electricity costs per unit.
