Digital isolator test related instruments and equipment can meet the requirements of IEC62132, IEC61967, IEC62215 and other electromagnetic compatibility test standards; also meet the requirements of VDE 0884-11/17, UL1577, IEC 60747-17, IEC 60747-5-5 and other safety test standards required to test the method of learning.
This paper mainly introduces the importance of electrical isolation in modern electronic design starting from the effect of different sizes of current on the human body, and introduces in detail the four isolation methods of electrical isolation such as magnetic isolation, capacitive isolation, optical isolation, and digital isolator.
In modern electronic equipment, high-voltage isolation technology is the key to ensure system safety and reliability. Digital isolators and optocoupler chips, as the main components to realize this high-voltage isolation, are widely used in power electronics, industrial automation, medical equipment and other fields. High-voltage isolation test methods are used to evaluate these devices in practical application...
This paper focuses on the definition of the test indicators Viso and Viotm in VDE 0884-11 or 17, the origin of the names, the test methods and the differences between the two different test methods.
This paper describes the importance of the new digital isolator test standard DIN VDE V 0884-11:2017-01 for the design of digital isolator chips.
This article is a detailed description of the test items required by the DIN V VDE V 0884-11 standard, which is the German certification standard for all digital isolators that are not optically isolated, and is used by major manufacturers of digital isolators such as TI and TOSHIBA for certification testing. There are also ...
When high voltage is added at the ends of the insulating medium, because of the existence of these bubbles or voids, a Qpd partial discharge (Qpd: Partial Discharge) will be generated. Slight partial discharges on the insulation of power equipment have a smaller impact, and the insulation strength decreases more slowly; while strong partial discharges, which will be...
This article describes the safety standards, standard definitions and test methods for digital isolators - high-voltage isolation testing to understand the high-voltage isolation parameters of maximum transient isolation voltage (VIOTM), isolation withstand voltage (VISO), maximum repetitive peak voltage (VIORM), operating voltage (VIOWM) ...
Understanding the definitions of High-voltage reinforced isolation parameters, their relevance to re...
