Patented Enhanced Hold-up Function Application Note
■When it comes to electronic equipment for rolling stock, EN 50155 is the most widely followed standard and is the gateway for power products to enter railway applications. It describes the conditions of input voltage, ambient temperature, isolation, interruption… etc. Compared with the general industrial application, the conditions are stricter in order to ensure the safety of public transportation and passengers. With the development of various industrial technologies and the requirements of miniaturization, it is a challenge for power modules and other electronic devices to realize "high reliability" and also meet requirements of regulations in harsh environment.
●The Advantages of Patented Enhanced Hold-up Function
■The same set of input voltage hold-up capacitors can be used for various system inputs. suffix “K”
■Choose 25V capacitors.
■Reduce the size of hold-up capacitors.
■Reduce the cost of hold-up capacitors.
■Reduce inrush current due to capacitance.
