Comprehensive analysis of a DC/DC half-bridge bidirectional boost converter with ZVS opportunity

A comprehensive analysis of a boost converter is presented in this article. Important data such as current and voltage estimations for the used components, characteristic numbers for semiconductor parts and an approximation of the expected power losses for a DC/DC half-bridge bidirectional boost converter with an LC output filter are carried out. A model from this converter is presented. The transfer functions for the output voltage and the current dependent on the duty cycle are calculated via a linearisation method. To decrease the power losses, the concept of zero voltage switching is used and explained. Future developments and applications are highlighted.
