Abstract :
Power stages can be connected in parallel to increase the output power. Whenever, it requires current sharing among phases, to optimize the design. A method to achieve the desired current sharing is with equalizing resistors, what it means power losses, or connecting converters with high impedance. In this work has been studied that input impedance of active clamp boost converters can work as a lossless equalizing resistor to achieve current sharing and benefits of soft switching can be added to the benefits of parallel association.
