Comparison of Forward and Flyback Power Supply Topologies

This technical bulletin explores the merits of forward and flyback power supply topologies, focusing on their design and performance trade-offs. It discusses active clamp forward and continuous conduction flyback isolated power supplies, particularly in the context of Power over Ethernet (PoE) applications. The document provides insights into parts count, output filtering, and the implications of each topology for telecom-oriented power supplies under the IEEE 802.3bt standard.
