In the field of power conversion and transmission, isolated DC/DC converters play a central role. These devices not only provide the necessary electrical isolation to protect sensitive equipment from high voltage risks, but also ensure the effective conversion and transmission of energy, meeting the high standards of power quality and stability required by modern electronic equipment.
Working principle and function
The basic working principle of isolated dc dc converters involves several key steps:
Input power isolation
Using components such as transformers, optocouplers or capacitors, the input and output ends are completely electrically isolated, effectively avoiding direct contact of current and ensuring the safety of the circuit.
Voltage conversion
With the help of advanced high-frequency switching technology, the converter can efficiently transfer power between different dc voltage levels. In addition, by adjusting the duty cycle, the stable level of the output voltage can be accurately controlled.
Voltage regulation process
Once the output voltage fluctuates, the converter will automatically adjust its internal settings, including frequency or pulse width, to ensure that the output voltage is stable near the preset value.
Application field
In environments where electrical isolation and precise voltage regulation are required, such as medical equipment, industrial automation control, and communication devices, isolated dc-dc converters play an important role. In addition, isolated Dc-Dc converters are also suitable for various DC power applications that require voltage conversion, especially various electric vehicles, such as electric forklifts, golf carts, tour buses, etc., and can also be used for voltage conversion of dc power sources such as solar/wind power.
Isolated dc dc converters play a vital role in many industries due to their excellent electrical isolation function and reliable power supply performance. Although various products have their own characteristics, their common goal is to provide users with more efficient and higher-quality solutions to better meet the growing market demand.
