Description
technical field [0001] The invention belongs to the technical field of controllers, and in particular relates to a circuit board used for a controller and a controller including the circuit board. Background technique [0002] A power semiconductor device is an electronic device whose conductivity is between a good conductor and an insulator, and uses the special electrical characteristics of semiconductor materials to complete specific functions. It can be used to generate, control, receive, transform, amplify signals, and perform energy conversion functions. . Commonly used power semiconductor devices include diodes, transistors, FRD devices, IGBT devices and rectifier bridge devices, which are widely used in various fields. [0003] For example, in the field of air conditioning, the circuit board of its controller needs to use more than two power semiconductor devices at the same time, such as IGBT devices (IGBT is the English abbreviation of Insulated Gate Bipolar Trans...
