Abstract
The contribution describes a maximum efficiency design of a push–pull (full-bridge and half-bridge) DC/DC converter transformer based on straightforward analytical calculations. The input parameters for the optimization are transformer core size, switching frequency and power. The output parameter is the core peak-to-peak flux density, from which all other essential parameters of the transformer (numbers of turns, core loss, winding loss etc.) can be derived. The optimization contains some simplifications which could cause a small error, but the result is an easy-to-use and simple to implement analytical formula, which can be used to quickly design a well-performing transformer or evaluate multiple designs.
