Ideal-Diode Devices Enhance Power-System Protection and Flexibility (.PDF Download)
March 31, 2021
Power systems employ diodes to perform a variety of functions. For example, diodes can protect against damage due to power-source reverse-polarity connections, as well as block reverse currents and transients. They also enable deployment of multiple power sources in parallel in an OR configuration to provide redundancy and load sharing.
Ideally, diodes for power systems would offer zero forward voltage drop and infinite reverse-current impedance. Although perfection isn’t achievable, several controllers and integrated devices allow you to implement ideal-diode functionality for your automotive, industrial, consumer, or other applications, thereby overcoming the limitations of the components traditionally used in power systems.
