数字隔离器的Qpd局部放电
Digital isolator and optocoupler

The importance of Qpd partial discharge test for digital isolators

The digital isolation chip is the core device of the high-voltage safety involved in the system, so it needs to be strictly screened when leaving the factory. The UL1577 safety standard clearly stipulates that when the product leaves the factory, it must be tested for 60s under the insulation withstand voltage condition or 1s under 1.2 times the insulation withstand voltage condition corresponding to the product specification. Only products that pass the high voltage test can leave the factory.
