Abstract
The minimization of size and losses are the main goals in the design of high power density and low output voltage onboard DC/DC power converters. Forward topology with resonant reset combines the simplicity of its power stage with the feasibility to implement self driven synchronous rectification. Several operation modes for this topology are proposed and analyzed in this paper: fixed frequency PWM and constant off-time variable frequency, with and without zero voltage switching (ZVS). Design guidelines and experimental results are also provided for 3.3 V output voltage converters, featuring efficiencies up to 90%.Keywords
