The switching power supply module can modularize the discrete components on the power supply, so that not only the power density is higher, but the volume is also smaller, and it is one of the common components on the current circuit. How to choose a good switching power supply module, we need to fi

The impedance characteristic of switching power supply module refers to that the power circuit composed of internal resistors, capacitors and inductors has blocking effect on AC current. The characteristic impedance of resistor is itself, and the resistance of capacitor and inductor to AC current is

1. Pay attention to power problemsFirst of all, there is the problem of power. Different power modules have different power. Some parts have a power of 3-300w, some parts have a power of 1-700w, and some parts have a power of 50-6000w. Only by purchasing such parts according to the needs of their ow

Power inverter (on-board power supply) is not only suitable for on-board system. As long as there is DC12V power supply, you can use the power inverter to convert DC12V into AC220V AC, which brings convenience to your life. 5. How does the high and low pressure alarm and shutdown function reflect? T

一、 Select from the rated withstand voltage value of the capacitor1. Selection of AC-DC rectifier filter capacitor withstand voltage value: in AC-DC rectifier filter circuit, according to the formulaWe can calculate the theoretical DC voltage after rectification.For example, in the rectifier circui

Power module current sharing refers to that two module power supplies with the same output current share the load equally, and the module power supply needs to undergo strict current sharing test before leaving the factory. If the power supply works under the same voltage, there is no need to adjust
