Romania the switching frequency of the AC-DC switching power supply module?(5)

●High quality and reliable. Module power supply generally adopts fully automatic production, and is equipped with high-tech production technology, so the quality is stable and reliable.
Wide range of uses: The modular power supply can be widely used in various fields of social production and life such as aerospace, locomotives and ships, military weapons, power generation and distribution, post and telecommunications, metallurgy and mining, automatic control, household appliances, instrumentation and scientific research experiments. In particular, it plays an irreplaceable and important role in the field of high reliability and high technology.

At present, the power carrier is mainly used for intelligent carrier in the home, remote meter reading system, and remote street lamp control system. The use range of the carrier frequency of power lines in my country is 9KHz ~ 500KHz, and the carrier bandwidth is 4KHz. The development of power carrier is very limited due to the change of power line impedance and the interference of power line noise. In order to increase the communication distance of the power carrier, we must move away from the power switching frequency of the circuit carrier unit. The carrier frequencies currently used in China are 115KHz and 132KHz. In this case, the switching frequency is around 60KHz for the Marine boost voltage power supply.
