Abstract) kakao i 다국어 번역 The power loss of the inverter acts as heat. Therefore, heat dissipation design is essential for high-output inverter operation. In this paper, a heat sink size optimization method applicable to all inverter module and heat sink structures is proposed. The capacity of the inverter was selected according to the load conditions, and the input power, output power, switching loss, conduction loss, case temperature, and junction maximum temperature were measured through simulation. Through this, the case temperature and junction temperature according to the loss of the inverter are found, and the appropriate heat sink size is suggested through heat dissipation simulation. The smaller the size of the heat sink, the higher the heat dissipation efficiency at the same power loss. However, if the temperature of the junction of the inverter becomes too high, operation is impossible. Therefore, we find out through simulation how high the operating temperature of the inverter can be with the minimum heat sink size. Create a 3D model of the inverter module and heat sink, apply the loss power derived through inverter simulation, and check the output temperature through simulation while reducing the size of the heat sink. Through this, a method for selecting the minimum size of the heat sink applicable to the inverter module was proposed.
