The present invention discloses a power supply semi-trailer for electric drive fracturing equipment, including a combination of a gas turbine engine, a generator and a rectifying unit, the generator outputs a winding configuration and a voltage required for the rectifying units directly to obviate conventional rectifier transformer equipment. The rectifying unit is connected to the inversion unit through a common DC bus, so that the common DC bus can separately drive multiple inversion units, thus decreasing the wirings of power supply lines. A high voltage inversion unit is disposed on a gooseneck of the electric drive semi-trailer to optimize the spatial arrangement of equipment. The entire power supply equipment has a compact structure, occupies a small area, and is simple in wiring.
A power supply semi-trailer for electric drive fracturing equipment, comprising a power supply semi-trailer body, one gas turbine engine, one generator and multiple sets of rectifying units, wherein the gas turbine engine, the generator and the rectifying units are integrated on the power supply semi-trailer body;
