A magnetic core testbed is intended to provide a variety of induction curves to fully characterize a magnetic material. Off the shelf solutions are prohibitively expensive and limited in testing range for research purposes. Mainly, high voltages and/ or currents and the ability to create a variety of induction profiles, beyond sinusoidal, is needed for full core characterization. This paper establishes...
This paper presents the design and magnetics optimization of 1-kW regulated LLC resonant converter with GaN FETs. By adopting the GaN FETs for primary side switches, the gate driver loss and turn-off loss are significantly reduced. A new structure of integrated transformer with stacked planar cores, shaped windings and synchronous rectifier MOSFET proposed to reduce the core loss and winding loss...
Scalar control has been the most popular control method implemented in induction machine drive systems. This paper presents an enhanced open-loop Volts-per-Hertz (V/f) controller aimed at strengthening the magnetizing flux of an induction machine when operated below its rated frequency. Instead of using the traditional constant V/f based on the idealized approximate steady-state machine model and/or...
