Hybrid CMOS/GaN 40-MHz Maximum 20-V Input DC–DC Multiphase Buck Converter

Hybrid CMOS/GaN 40-MHz Maximum 20-V Input DC-DC Multiphase Buck Converter

This paper presents a 40-MHz hybrid CMOS/GaN integrated multiphase dc–dc switched-inductor buck converter with a maximum 20-V input voltage. The half-bridge switches are realized using lateral AlGaN/GaN HEMTs, while the drivers and other circuitry are implemented in standard 180-nm CMOS. The interface between the CMOS and GaN dice is achieved through face-to-face bonding, reducing inductive par...

A Cell-Based Multiphase Interleaving Buck Converter with Bypass Capacitors

Today’s Voltage Regulator Modules (VRMs) face increasing design challenges as the number of transistors in microprocessors increases per Moore’s Law. These challenges have recently become even more demanding as microprocessors operate at sub voltage range at significantly high current. This paper presents a new multiphase topology with cell configuration for improved performance in low voltage ...

Two Input Positive Dc-dc Buck-boost Converter Topology

A new multiple-input hybrid energy conversion topology is presented. The proposed topology is capable of combining different energy sources with different voltagecurrent characteristics, while achieving low part number and bi-directional operational. The Multiple-input converters have many applications such as grid connected integrated hybrid generation systems, fuel cells, micro grid-based tel...

Hybrid Fuzzy-pid Controller in Buck-boost Converter

Different types of controlling methods are used in switched mode dc-dc converters and the controller which is simple and of low cost is always in demand. The different controllers used are PI controller, PID controller and Fuzzy logic controller. PI and PID controllers do not give good performance in non linear conditions. Fuzzy logic controller is a non linear controller which do not need exac...
