AI Technical Summary
Existing data center power conversion systems cannot achieve rapid switching, resulting in power outages when AC power fails, and mechanical switches cannot meet reliability and cost requirements.
The system employs a dual-input power conversion system, which includes a primary-side power network coupled between the first and second AC power sources and the primary winding of the transformer, connected to the secondary-side power network via a magnetic coupling device, and uses a power converter to power the load. The system controller detects and enables or disables the power factor correction device to achieve rapid switching.
It enables rapid power switching in the event of an AC power failure, improving the reliability and economy of data center power systems and reducing the need for large-capacity holding capacitors.
