Abstract
The invention relates to a surface-mounted metal oxide semiconductor field effect transistor (MOSFET) inversion module technology for the power of a motor controller of a new energy automobile. An inversion module consists of insulated gate bipolar transistors (IGBT) or single MOSFETs in surface-mounted packages on an aluminum substrate. Copper-clad wires printed on the aluminum substrate are used for all connection, and other accessory wires are not required. A drive balance circuit is arranged on each IGBT or each single MOSFET, and is arranged on an independent printed circuit board (PCB). The PCB with the drive balance circuit is sleeved on the IGBTs or the single MOSFETs. The drive balance circuit is independently arranged on the independent PCB, and the PCB is sleeved on the IGBTs or the single MOSFETs, so that the drive of each IGBT or each single MOSFET is close to the IGBT or the single MOSFET to realize high consistency; and moreover, the IGBTs or the single MOSFETs are in close fit, so that a space is reduced, and cost is lowered.
