Usage Of Pulse-Edge Transformer In Secondary-Controlled Flyback Applications

As the demand for smaller form factors and higher energy efficiency for charger/adapter grows, the wide bandgap (WBG) device technology is gaining popularity. To use the potential of WBG and thus improve the power density and efficiency, the switching frequency levels of converters are in the order of 300 kHz to 400 kHz. The higher switching frequency also requires faster control or response ti... » read more

Protecting Power Management Circuits Against Trojan Attacks

A technical paper titled “Hardware Trojans in Power Conversion Circuits” was published by researchers at UC Davis. Abstract: "This report investigates the potential impact of a Trojan attack on power conversion circuits, specifically a switching signal attack designed to trigger a locking of the pulse width modulation (PWM) signal that goes to a power field-effect transistor (FET). The fi... » read more
