Four types of isolation for electrical isolation

Four types of isolation for electrical isolation

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.

High Voltage Isolation Test Methods for Digital Isolators and Optocoupler Chips

High Voltage Isolation Test Methods for Digital Isolators and Optocoupler Chips

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...

DIN V VDE V 0884-11 (VDE V 0884-11): 2017-01 Certification Test Program Overview

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 ...

Qpd Why is partial discharge testing necessary for digital isolators?

Qpd Why is partial discharge testing necessary for digital isolators?

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...
