DC DC power module is a power module that converts DC power into DC power. At this time, many people may have to ask, is it unnecessary to convert DC to DC? In fact, in the daily use of the process, our current is not static, sometimes need high voltage, sometimes need low voltage. The DC DC power module is to convert the high-voltage or low-voltage current into the pressure we need. Its working principle is to convert DC power into AC power, it will convert AC power into DC power we need.
In the process of daily use, because the DC DC power module is completed by switching oscillation circuit, it will also produce common mode differential mode noise interference. Therefore, in the process of using, we need to pay attention to the current value, preferably more than twice the input current value. The internal resistance of the power supply should be small, so as to reduce the consumption of DC. And in order to ensure that the power supply module has a strong reliability in the long-term work, it should work at more than 10% of the rated power, so as to avoid the voltage instability caused by the module trapped or slight output, which affects our work.
Many customers in the process of using the power module, is to achieve the isolation of power. Then according to different isolation requirements, we need to choose different power supply, and there is enough circuit distance between the output and input power supply in the design, so as to avoid weakening the effect of isolation.
