Abstract

The utility model belongs to the field of high-power high-frequency inverter power supply equipment, and particularly relates to a power unit based on a SiC module power device, which comprises a unit box shell and a laminated busbar, a direct current input bar is reserved on one side of the unit box shell, the laminated busbar is arranged in the unit box shell, an SIC MOSFET module is arranged on the laminated busbar, and the SIC MOSFET module is arranged on the other side of the unit box shell. One end of the SIC MOSFET module penetrates through the opposite side of the direct current input bar of the unit box shell, the direct current input bar and the SIC MOSFET module are in electrical loop communication through a laminated busbar, and a direct current supporting capacitor is arranged on the laminated busbar close to the direct current input bar; sIC MOSFET driving boards are arranged on the two sides of the direct-current supporting capacitor, and driving power panels are arranged on the unit box shell close to the SIC MOSFET driving boards respectively. And absorption capacitors are uniformly distributed on the laminated busbar, and a power supply and a fan are arranged above the unit box shell. The internal electrical layout of the power unit is more reasonable and compact, smaller space occupation is realized, and the overall working reliability and stability of equipment are improved.
