Abstract
The present invention discloses an electric drive fracturing power supply semi-trailer, which can separately drive multiple high voltage inversion units and multiple low voltage inversion unit, through a common DC bus, by employing a high voltage switch, a transformer and two sets of rectifying units. The electric drive fracturing power supply semi-trailer is small in size, compact in layout and economical. The high voltage switch, the transformer, and the rectifying units are shared to decrease the wirings of power supply lines, thus reducing the number of equipment and capital investment, and better meeting the usage requirements.
