Comparative Analysis of Dual-Output Controlled Rectifiers in Small Domestic Appliances Powered by Wireless Power Transfer

The development of induction heating cooktops towards more versatile transmitters for wireless power transfer aims for the cordless powering of small domestic appliances through inductive coupling. Among those appliances, the ones that present multiple actuators, i.e. cooking robots or air friers, require independent voltage levels to control each subsystem of them. This paper presents several implementations of dual-output controlled rectifiers for small domestic appliances and stablishes the figures of merit to compare them.
