摘要（英）：

The invention discloses a high-power direct-current power supply, which mainly includes a rectifier and filter module, a current transformation module, a voltage transformation module, an output module, a current and voltage detection module, a control module and a drive module. A three-phase alternating current is input to the rectifier and filter module, the output of the rectifier and filter module is output to the output module through the current transformation module and the voltage transformation module, the current and voltage detection module feeds back the detected current and voltage signals to the control module, and the control module makes the drive module drive the current transformation module, so as to achieve high-power direct-current stable output. A high-power direct-current power supply with high conversion efficiency, low power consumption, simple structure and stable output is realized by utilizing the high switching frequency characteristic of insulated gate bipolar transistor (IGBT) devices.
