Switching power supply is a seemingly simple but complex electronic system. It contains many interesting questions.Generally speaking, the output voltage and input voltage of a voltage reduction system are calculated based on the duty cycle of the switch. For example, if the input is 24V and t

1. What is the function of a 24V power module?The functions of the 24V power module are mainly reflected in the following aspects:1. Isolation effect, which can achieve safety isolation, noise isolation, and elimination of grounding circuits;2. Overcurrent protection, undervoltage protection, overvo

The factors that affect the reliability of power supply products include design, process, management, testing and methods, feeding, etc. These are all issues of concern to power module manufacturers and users. In fact, the reliability of power modules not only requires optimization of various perfor

1. What is the reason for the power module burning out?Based on the on-site situation and circuit diagram analysis, it can be concluded that the cause of the power module burning is a short circuit caused by U1 and its series resistor R4.2. The consequences of burning out the power moduleThe power m

The following are the three elements of a low ripple power supply:1. Energy storage inductance. The larger the Q value of the energy storage inductance at the working frequency, the better. Many people only pay attention to the inductance. In fact, the influence of Q value is much larger. As long as

In the modern high-tech era, the higher the reliability of DC-DC power modules, but AC-DC power conversion and DC-DC power conversion have gradually become module or integrated chip industry, and also gradually become an important part of various electronic equipment and industrial automatic control

1. SecurityIsolated DCDC power module refers to the isolated power supply that uses transformers to reduce the voltage of various voltages (such as 48VDC, 24VDC, 12VDC, etc.) to the required voltage through transformers, and then supplies power to the load. The non isolated power supply module direc

Isolation power supply: Isolation power supply refers to reducing the high voltage to low voltage through the transformer, and rectifying it into a DC voltage. Since the whole conversion process is not connected to the ground, it is not easy to have the risk of electric shock accident, and it is saf

For dcdc module power products with TRIM or ADJ (adjustable) output pins, the output working voltage can be adjusted within a certain range according to resistors or adjustable potentiometers, usually the adjustment range is ±10%.For the TRIM output pin, connect the potentiometer to TRIM. In all mo

The key is to confirm the cleanliness of the power module, which requires accurate measurement of the output ripple of the dc-dc power module. However, the ripple value obtained by many people's accurate measurement is hundreds of mV, or even hundreds of mV, which is far higher than the larger r
