A four-chip parallel IGBT module based on the latest generation technology used in Photovoltaic Centralized Inverter

Inhalt:
This paper introduces the application of four-chip parallel IGBT module using the 7th generation of chip technology in photovoltaic centralized inverter. There are not many products worldwide that can achieve four chip parallel connection. Parallel connection of four chips puts forward high requirements for chip consistency. In addition, the power loss of each part is accurately calculated, and the total loss of our module is more than 5% lower than other competitive products on the market. This product is able to support the working temperature of 175 °C, and has high reliability in special application scenarios.
