DC AC Switch Mode Power Supply ct Power Supply Companies Power Supply for CT

D.C. to D.C. converters and D.C. to A.C. Converters belong to the category of Switched Mode Power Supplies (SMPS). The various types of voltage regulators, used in Linear Power Supplies (LPS), fall in the category of dissipative regulator, as they have a voltage control element usually transistor or zener diode which dissipates power equal to the voltage difference between an unregulated input voltage and a fixed supply voltage multiplied by the current flowing through it. The switching regulator acts as a continuously variable power converter and hence its efficiency is negligibly affected by the voltage difference. Hence the switching regulator is also known as ‘non-dissipative regulator’.

Introduction:

CT power taking device is a new type of induction power taking device that uses electromagnetic energy induced around high-voltage transmission lines to obtain electrical energy. This device uses the principle of electromagnetic induction, uses a current transformer to directly induce AC voltage from the high-voltage bus, and then undergoes rectification, filtering, and voltage stabilization to obtain a stable and reliable DC voltage to provide a stable power supply for electrical equipment installed nearby. It can ensure the long-term stable power supply of the load equipment. It is suitable as a power supply device for on-line detection, monitoring, inspection, anti-theft and other electrical equipment on high-voltage transmission lines.
