Embodiment

[0043] As attached figure 1 As shown, a topological high-frequency and high-voltage energy transmission system of the present invention includes a high-frequency double-pulse power supply, three high-frequency and high-voltage transformers, and three energy transmission sensors.

[0044] Among them: the input end of the high-frequency dual-pulse power supply can be connected to a wide range (DC180V~DC260V) DC voltage and AC mains (AC180V~AC260V) at the same time, and the input voltage is internally processed and transformed into three groups of amplitude and frequency. The high frequency double pulse voltage is output to three high frequency high voltage transformers; each of the secondary side is connected to an energy transmission sensor, which is a high permeability, high frequency energy transmission sensor; the internal high frequency current energy transmission sensor of the energy transmission sensor The number of units can be flexibly configured by the size of the high-fr...

Abstract

The invention relates to a system and a method for topology high-frequency high-voltage energy transmission. The system comprises a high-frequency dipulse power supply, a high-frequency high-voltage transformer and an energy transmission sensor which are connected in sequence. The method includes (1) accessing the high-frequency dipulse power supply to the low-voltage mains supply and / or low-voltage direct current power, and (2) converting the access voltage into high-frequency voltage or current to output to the high-frequency high-voltage transformer. The system has the advantages of accurate energy transmission, high energy efficiency, stable and reliable operation, high electric-isolation voltage class, high load compatibility, small size, light weight and the like.
