Development trend of TH230D10NZ-D 220v series high frequency switching power supply


Th230d10nz-d 220V series high frequency switching power supply, as a high-quality high-frequency switching power supply product, has already had relatively excellent performance, but this series of products also have long-term development prospects.

High frequency

Theoretical analysis and practical experience show that the volume weight of transformer, inductor and capacitor of high frequency switching power supply is inversely proportional to the square root of power supply frequency. Therefore, when we increase the frequency from 50 Hz to 20 kHz by 400 times, the volume and weight of high frequency switching power supply will be reduced to 5 ~ 10% of the power frequency design. Th230d10nz-d 220V series high frequency switching power supply is also applicable to this principle.

modularization

Modularization has two meanings, one is the modularization of power devices, the other is the modularization of power supply units. Our common device modules, including one unit, two units, six units to seven units, including switching devices and freewheeling diodes in reverse parallel, are essentially "standard" power modules (SPM). Some companies put the drive and protection circuit of high frequency switching power supply into the power module to form the "intelligent" power module (IPM), which not only reduces the volume of the whole machine, but also facilitates the design and manufacture of the whole machine. The components of th230d10nz-d 220V series high frequency switching power supply are also suitable for the further development of modularization.

Greening

Green power system has two meanings: first, significant power saving, which means saving power generation capacity, and power generation is an important cause of environmental pollution, so power saving can reduce environmental pollution; Secondly, these power sources can not (or less) pollute the power grid. The International Electrotechnical Commission (IEC) has formulated a series of standards, such as iec555, iec917, iec1000 and so on. Th230d10nz-d 220 V series high frequency switching power supply will continue to strengthen green development in the future.
