Abstract
A power supply circuit includes two half bridge circuits, a controller and two terminals for connecting a motor. The controller includes a signal input terminal, a phase inverter, a wiring board having four soldering pads, and two conductors. The four soldering pads are connected to the signal terminal, an output terminal of the phase inverter, control terminals of lower switches of the two half bridge circuits. Two ends of the first conductor are connected to the first and the fourth soldering pads and two ends of the second conductor are connected to the second and the third soldering pads. Alternatively, two ends of the first conductor are connected to the first and the third soldering pads and two ends of the second conductor are connected to the second and the fourth soldering pads.
