[0002] The speed and power characteristics of integrated circuits depend on the power supply voltage. In order for the circuit to work reliably while meeting the target performance specifications, a stable power supply voltage is required. In most electronic systems, there are several circuits that require different voltages and currents. In order to provide different voltages, currents and rated powers to these circuits, a voltage converter is required to make the voltage meet the requirements of the low-voltage power supply, which is usually less than 36V. Low-voltage power supply products are basic components of the machinery industry, and the performance and quality of its products directly affect the reliable operation of power systems and industrial control systems.

[0003] In the existing technology, heat generation is one of the factors that affect the stable operation of low-voltage power supplies. A low-voltage power supply product with excellent performance should have good heat dissipation capabilities. At present, a common heat dissipation method used by low-voltage power supplies is to install a fan on the power supply to remove heat through air flow. Although this heat dissipation method can improve the heat dissipation efficiency of the power supply, the heat dissipation method is too simple. When the room temperature is high or the power supply is heated, the heat dissipation effect of the power supply is poor, and it still cannot meet the normal use of low-voltage power supply products.
