Abstract

{Isolated components are widely used in High Voltage (HV) applications to protect users from dangerous voltages. However, it's usually confusing to know key considerations, such as isolation voltage, working voltage, clearance, creepage and certificate etc., and to select the most suitable isolated devices. This application note series can help engineers understand safety requirements and isolation needs for HV application, how to design the whole system isolation to satisfy the corresponding safety standards, and finally choose the right isolated devices. The series includes 3 parts, part II focuses on topics of key considerations to select the most suitable ISO devices and deep understanding on how clearance and creepage distance are required for ISO devices.
