For many people who have not counted the power supply or the power supply design has not yet reached the project development capability, how to design a good switching power supply? We can regard the power supply board as a unified body, and then use the common circuit to fight . This will lead to a good product. For new products, you should use your own understanding and sure circuit! If not, the products designed will have a lot of problems in production! The following power adapter manufacturers explain to you:
1. Determine your power supply and input voltage. The switching current, the transformer volume, and the input voltage of the power supply selection switch tube determine the withstand voltage of the switch tube and the number of input coils of the transformer.
2. It is necessary to select a suitable switching frequency to ensure that the static loss is minimal and the field tube conversion efficiency is the highest.
3. Regardless of the voltage, power supply, the field tube must have a low-pass discharge and fast charging circuit.
4. The transformer must have an absorbing circuit to absorb the harmonics.
5. The internal resistance of the field tube gate should be pulled low with the resistor ground.
6. When the power is too large, it is necessary to filter the PFC circuit into the design.
7. The drive signal should be stable! It must have more than 5V.
8. When the input voltage exceeds 75V, the filter resonant circuit should be tested as a negative assist function circuit.
Heavy-duty connectors are designed to withstand the harshest and most demanding industrial environments, and are tougher, stronger, and more resistant than conventional connectors. Compared with traditional connection method, using heavy-duty connector can save 20-30% installation cost for machining center; Increased production efficiency, and reduce wiring error rate.
