Abstract

The invention provides an electric leakage protection circuit and method and an applicative driving device. The electric leakage protection circuit is used for achieving electric connection with a power supply line of a load, conducting spaced sampling on the power supply line, detecting the voltage of a sample electric signal so as to determine whether the voltage of an alternating-current inputpower supply is divided or not, and providing electric leakage protection based on determined results. The electric leakage protection circuit determines whether the voltage of the connected alternating-current input power supply is divided or not through spaced sampling conducted on the voltage of the power supply line and voltage dividing detection. When voltage division is determined, the powersupply line is disconnected, and electric leakage protection of the human body mistakenly undergoing electric shock and the load is achieved.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, in particular to a leakage protection circuit, a method and an applicable driving device. Background technique [0002] When people insert one end of the LED fluorescent tube into the slot of the fluorescent tube frame, people may focus on assembling the needle-like pins of the LED fluorescent lamp and ignore the position of the handheld lamp. When one end of the fluorescent lamp is inserted into the slot of the fluorescent tube frame, the There is a danger of electric shock by touching the other end of the LED fluorescent lamp that is not inserted into the slot on the fluorescent tube frame with your finger. Contents of the invention [0003] In view of the shortcomings of the prior art described above, the purpose of this application is to provide a leakage protection circuit, method and applicable driving device for solving the problem of leakage caused by accidental co...
