Adjustable-voltage-ratio (AVR) magnetoelectric transformer is a new type of power transformer whose voltage ratio between the output and input can be adjusted continuously from the minimum value (e.g., zero) to the maximum value designed. Therefore, given an input voltage with fixed amplitude, the AVR transformer can output one or multiple AC voltages with continuously adjustable amplitudes from zero...
This paper presents a novel adjustable-voltage-ratio (AVR) transformer made using magneto-electric materials. Given a fixed-amplitude alternating current voltage input, the AVR transformer can output an ac voltage whose amplitude can be adjusted continuously from zero volts to the maximum value determined by the design. The core(s) of the AVR transformer are laminated and made of bonded layers of...
