摘要：
Paralleling converters is a good choice for designing high frequency and high power converters. Nevertheless there must be a mechanism to share the load among phases to achieve all the benefits of parallel operation. A simple method to achieve current sharing is paralleling converters with high impedance. The ZVT Boost converter has interesting properties: Zero Voltage Transition, less semiconductors stress and high input impedance, what can be used as a passive lossless current sharing method. It has been analyzed in this paper, getting a complete model, where the impedance has been studied. A 2-stages 600 W prototype has been designed to test the current sharing.
