Description

Non-polar surge suppression integrated single element with voltage control regulator {One Chip Surge Arrester with Selector Switch}

The present invention relates to a non-polar surge suppression integrated single element having a voltage control regulator that can limit the surge voltage to a very low residual voltage or less in stepping without frequency attenuation when a surge of high voltage and large current is introduced.

Lightning strikes about 360,000 times every hour around the world with breakdown forces and wide frequency components that can generate large surge currents and transient voltages. Peak currents range from a few [kA] to 150 [kA] to 20 [kA]. The inside and outside account for about 50 [%].

In particular, lightning is divided into direct strike and indirect lighting according to the type of lightning discharge, and when the lightning strike enters the device, it is difficult to protect the device and human life. The damage caused by direct lightning strikes shall be primarily protected by the installation of lightning rods at appropriate protection points, and the communication surge protectors shall protect the protected devices against surge voltages which minimize the insertion loss under normal conditions. For this purpose, the surge protector for communication shall satisfy the small input capacitance in the circuit, the high-speed operation characteristics against the surge voltage, and the surge resistance sufficient to protect the protected object.

Surge is a transient of electrical current, voltage, or power that is transmitted along a line or circuit and has a rapidly increasing and decreasing nature. Surge is a phenomenon that occurs when lightning strikes around us, and there are various kinds and characteristics, so the protection measures are not fully established. In recent years, as the directivity of semiconductors increases, the circuit width inside the semiconductors becomes narrower, and because the conductive material is used to operate at low voltage, the short circuit phenomenon is lowered, so that the system incorporating many semiconductors becomes weak to breakdown voltage. The risk of surge damage also increases. The impact of a surge on the system is a type of stress, and repeated small surges degrade the device and cause chronic damage, while strong surges make it irreparable at once. In particular, as the development of advanced science and technology has accelerated, semiconductors have been widely used in the fields of electricity and electronics, and as a result, the damage caused by surges has been increasing and increasing.

Patent techniques that have been proposed in Korea and abroad to overcome this problem, an overvoltage absorber using a conductive line substrate absorbing the overvoltage between the counter electrode (Korea Patent Publication No. 1998-0012417 / 1998. 04. 30) [Fig. (A) Reference], surge absorption circuit which absorbs surge by connecting surge absorption element in parallel between input terminal, output terminal and common terminal (Japanese Patent Laid-Open No. 2006-174601 / 2006. 06. 29) [Fig. Reference], surge absorber overcurrent circuit breaker that connects thermal fuse and high-energy varistor in series to make parallel circuit at the inlet of AC voltage and discharges it to earth (Korea Utility Model No. 20-2008-0000552 / 2008. 04 21) (see Fig. 1 (C)).

However, most of the conventional lightning protection devices for lightning protection do not completely remove surge energy remaining in the device by inter-discharge or absorption discharge in the device. .

On the other hand, the electric device may be exposed to a high voltage or a power overload risk of the AC main power input terminal due to a transient current caused by a lightning strike or a transient phenomenon of power plant load switching. The international standard for testing the voltage and current conditions of equipment connected to the AC mains is IEC 61000-4-5. The surge immunity of the AC mains equipment is tested using a composite waveform of 1.2 [kV] rise / 50 [kV] fall cycle and 8 [kV] rise / 20 [kV] fall cycle, regardless of installation class. Some electrical and datacom equipment have different rise / fall cycles, but all AC mains devices are tested with this combination of waveforms.

The combination of overcurrent and overvoltage devices at the AC mains input allows designers to comply with safety agency requirements and reduce component count and cost.

SUMMARY OF THE INVENTION In order to overcome the above-mentioned problems, an object of the present invention is to provide a transient voltage surge flowing at high speed without frequency attenuation through a voltage / current limiting element connected in series and in parallel with a crowba switching element. The present invention provides a non-polar surge suppression integrated single device having a voltage control regulator which is reduced in steps over several steps and completely eliminates some transient voltage / current remaining in the device and connects to the circuit in a non-polar manner.

However, in the event of an overvoltage surge, such as a lightning strike, the GDA transitions to a low impedance state, allowing it to pass through sensitive equipment.

 As such, GDA is a device that is widely used as a surge protector for communication because of its small internal capacitance. However, GDA operation requires sufficient voltage and time to start discharging. This operation start voltage is large enough to damage when the protected circuit is a surge-sensitive device. In most cases. In the GDA where a large initial overvoltage exists, it is necessary to add a filter or another circuit to limit the peak voltage.
