Abstract: A novel dual-output magnetoelectric (ME) gyrator operating in an acoustic resonance mode and based on a Pb(Zr x Ti 1− x )O 3 (PZT)/Metglas/PZT ( P–M–P ) trilayer structure is discussed. The dual-output with different current-to-voltage ( I–V ) conversion ratios and different voltage levels result from the use of piezoelectric layers with different thicknesses as the output capacitive port. Under open circuit conditions, the maximum I–V conversion ratios of the two outputs were 5.7 and 13.5 kV A −1 at a frequency of 50.4 kHz. A high power efficiency ( ƞ ) of 91.7% was achieved and remained relatively stable (⩾86%) under increasing power drive to a power density of 45 W in −3 . These excellent power transfer and multi-output characteristics offer unique possibilities for possible use of ME gyrators in modern power electronic devices.
