Problems that should be paid attention to when designing reliable guanjian5(3)


Module power

The loss of high-power module switching power supply mainly includes four parts: high-frequency switching loss, high-frequency transformer loss, rectification loss and line conduction loss. In the application of low voltage and high current output, the rectification loss and line conduction loss account for a larger proportion. .

There are many manufacturing industries in which power modules are used, and the requirements of the natural environment are different. Because of its universal design, DC-DC power modules can only consider the general requirements. Therefore, when customers' application scenarios are demanding, it is necessary to add appropriate peripheral power circuits to improve the stability of the Marine boost/buck voltage power supply.

4. Heat dissipation design

About 15% of the destruction of industrial power modules is caused by poor heat dissipation of heat pipes. The power modules are moving towards miniaturization and integration. However, the Marine boost/buck voltage power supply in many application places is constantly operating in a closed environment. If the accumulated heat cannot be dissipated, the components inside the Marine boost/buck voltage power supply will be destroyed due to exceeding the thermal stress.
