Abstract

A multiphase converter can be used for high-current applications using smaller rated devices. Due to the parallel connected structure of a multiphase converter, the required output current is produced by coupled inductors reducing the current stress when compared to a conventional DC-DC converter which possesses only a single inductor. This makes the multiphase converter a lot cheaper and compact in size. However, to ensure equal current distribution across the coupled inductors, a balancing current controller with additional current sensors is required. This will greatly impact the efficiency of the multiphase converter. Due to this, researchers have proposed numerous current sensing techniques for the multiphase converter. The proposed techniques are immune to I2R loss, increasing the efficiency of the multiphase converter. For this reason, a parallel voltage sensing technique is presented for a four-phase multiphase converter using digital RC network. This method is base on modifying the conventional RC sensing technique without using any external circuit.
