“…Cooling technologies are being developed with integrated motor drives [85]. The recent literature has shown interest in WBG inverters for integrated solutions [112][113][114][115], in which air cooling can be applied for low-power motor drives. For instance, Dai et al shared an air-cooled IMD concept in which the operation procedure of the air-cooling system is as follows: (1) inlet air is first drawn radially across the heat sink, which conducts heat out of the power modules; (2) the air is then pulled axially through the motor's airgap to cool the machine.…”

The development of electric vehicles (EVs) is an important step towards clean and green cities. An electric powertrain provides power to the vehicle and consists of a charger, a battery, an inverter, and a motor as the main components. Supplied by a battery pack, the automotive inverter manages the power of the motor. EVs require a highly efficient inverter, which satisfies low cost, size, and weight requirements. One approach to meeting these requirements is to use the new wide-bandgap (WBG) semiconductors, which are being widely investigated in the industry as an alternative to silicon switches. WBG devices have superior intrinsic properties, such as high thermal flux, of up to 120 W/cm2 (on average); junction temperature of 175–200 °C; blocking voltage limit of about 6.5 kV; switching frequency about 20-fold higher than that of Si; and up to 73% lower switching losses with a lower conduction voltage drop. This study presents a review of WBG-based inverter cooling systems to investigate trends in cooling techniques and changes associated with the use of WBG devices. The aim is to consider suitable cooling techniques for WBG inverters at different power levels.
