Forward and flyback power supplies have unique characteristics for different applications.We discuss the characteristics of active-clamp forward and continuous-conduction flyback isolated power supply topologies and demonstrate the design and performance trade-offs of each using two telecom-oriented power supplies as examples. Brief overviews of each topology are provided to aid in…

Primary frequency response (PFR) is an important mechanism for making power grids resilient to faults that could lead to outages. We present the first study of cyberattacks that could cause power outages by infiltrating operational technology networks in generation control systems to inhibit the PFR. Source: New feed
