This paper presents the design and implementation of a new integrated circuit (IC) that is suitable for driving the new generation of high-frequency GaN HFETs. The circuit, based upon a resonant switching transition technique, is first briefly described and then discussed in detail, focusing on the design process practical considerations. A new level-shifter topology, used to generate the zero and...
The paper describes a high-speed high efficiency H-bridge circuit based upon Gallium nitride (GaN) Heterostructure Field-Effect Transistor (HFET) devices as power switches. The use of a new designed driver integrated circuit (IC) makes it possible to exploit the capabilities and advantages of GaN technology in power electronic applications by means of a smart and convenient implementation. Low power...
A switched-capacitor programmable filter is proposed as educational tool for the feedback compensation of power converters. The transfer function of the external feedback network, expressed in the Z-transform domain, can be assigned by means of Multiplying DACs. The cancellation of poles and zeros of switching power cells is precisely implemented even in the case they are complex. An ideal final single...
The exigency of a rapid prototyping of power converters represents an important issue for the power electronics market and pushes the designer toward the search of software tools able to depict the static and dynamic behavior of the electrical circuits. The availability of reliable analysis tools open the possibility to their use not only for the design but also for the test of the converters in circumstances...
A multi-agent framework for monitoring and control of power electronics systems may comprise agents with different tasks: strictly measurement, control, computation, decision making, simulation and more. Each task is best performed within a dedicated environment: LabVIEW, Matlab, custom simulators and more. The focus of this work is a heterogeneous agent-based monitoring and control system; the aim...
