Latest Patents

The supplied information identifies one patent for Qing Ye: “AC/DC Substation Configurable Between Charging and Powering Modes.” The invention describes a portable substation that converts medium-voltage AC grid power into DC power and can be configured for either battery charging or motor operation.

The substation uses two DC power converters, each built from three-phase transformers and a single stage of silicon-controlled rectifier units. Adjustable connectors allow the converters to operate in parallel for battery charging, delivering up to 4,800 ADC at 6 MW, or to provide up to 1,500 VDC. In series, the converters can supply up to 3,000 VDC at 6 MW to power machine motors. Designed to fit inside a standard high-cube ISO shipping container, the system emphasizes portability, high power density, and low cost per kilowatt. The supplied data lists 1 patent.
