Abstract

Magnetic refrigeration (MR) is making use of magnetocaloric (MCE) effect to refrigerate with the advantages of high efficiency, low energy consumption, and being environmentally benign. In this paper, the design of a uni-polar controllable intensity of magnetic field supply unit is described and implemented to improve the adjusting capability of magnetic filed, H, for generating the related effect of magnetic field that applied and removal in MR to cool down systems. The proposed magnetic field supply unit, taking the coils as loading, is composed of full-bridge PWM control inverter circuit, coupling transformer, and rectifier; thereby the controllable DC current can be outputted to make the total magnetic field be regulated by the producing H based on the magnetic core with wound coils. Simulation results demonstrate the feasibility of the presented structure, and the experimental results show the effectiveness of the controllable H ranges from 0.667 Tesla to 1.07 Tesla as well.
