Abstract

A power supply circuit includes a printed circuit board (PCB), and a transformer coupled to the PCB. The power supply circuit also includes a first inductor assembly coupled to the PCB and electrically connected to the transformer, and a second inductor assembly coupled to the PCB and electrically connected to the transformer. The first inductor assembly has an inner edge and an opposite outer edge, and the second inductor assembly has an inner edge and an opposite outer edge. The inner edge of the second inductor assembly is spaced apart from the inner edge of the first inductor assembly by a gap. The power supply circuit also includes a first magnetic shunt coupled to the outer edge of the first inductor assembly, and a second magnetic shunt coupled to the outer edge of the second inductor assembly.
