How to design a reliable and safe buck module power supply(3)

Correctly control the components to the specified value, reduce the number of components to delay degradation, improve component reliability and improve power reliability.

3. Dual buck module power supply planning

●Low technical requirements. Modular power supplies are typically equipped with standardized front ends, highly integrated power modules and other components, thus simplifying power supply design.
●The module power supply shell has a three-in-one structure of heat sink, radiator and shell, which realizes the conduction cooling mode of the module power supply and makes the temperature value of the power supply approach the minimum value. At the same time, the normative packaging of the module power supply is given.

The output of the bidirectional power module should pay attention to the load balance. When planning, pay attention to the main and auxiliary circuits to adjust the output evenly.

4. Component selection

The use of different components will result in different module functions. For example, ceramic or electrolytic capacitors are generally used for capacitor selection, while tantalum capacitors have long life, high temperature resistance, good functions, but simply break the circuit. Please note that different products use different methods.
