Abstract
An apparatus includes, on a top layer of a circuit board, a first and a second synchronous rectifier groups (SRGs) placed along first two opposite sides of a first phase of a transformer including three phases. A second and a fourth SRGs are placed along the first two opposite sides on a bottom layer of the circuit board. The first and second SRGs are connected between a first terminal of the first phase and a grounding terminal. The third and fourth SRGs are connected between a second terminal of the first phase and the grounding terminal. Two filter capacitor groups are placed along second two opposite sides of the first phase on the top layer. Another two filter capacitor groups are placed along the second two opposite sides on the bottom layer. The four filter capacitor groups are connected to a third terminal of the first phase.
