Abstract :
The goal of this paper is to design and test a "universal" low power (10 W) converter that can be fed from a very wide input voltage range (36 V-373 V), being possible to plug it in different power systems. Flyback with Active Clamp shows very good performance for this application and is used to test a 150 kHz, 5 V, 10 W prototype that operates even for a 1:20 input voltage ratio (18 V-373 V)
