Most high-power inverters and their associated electronic components are integrated into electrical cabinets. Inverters not only improve system efficiency, but the efficiency of the inverter itself is also very high, with a loss of only 2% to 4%. However, due to the large amount of power conversion in high-power inverters, even if the efficiency loss is low, it will lead to the generation of several kilowatts to tens of kilowatts of waste heat, which must be dissipated....
