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

Usage Of Pulse-Edge Transformer In Secondary Controlled Flyback Applications


The pulse-edge transformer (PET) is used as a medium to transmit PWM pulses from a secondary-side controller, such as EZ-PD™ PAGxS, to a primary-side controller, such as EZ-PD™ PAGxP, for AC/DC applications targeting the power adapter segment. This article explains the advantages of PET over the conventional opto-coupler based approach. Click here to read more. » read more
