Abstract

An apparatus includes a power converter to convert incoming alternating current (AC) mains power into a direct current (DC) voltage. A linear AC pump of the apparatus has an arm that reciprocates linearly back and forth to move a pair of diaphragms to pressurize air that is output from the linear AC pump. The apparatus also includes a DC motor driver having an H-bridge that receives the DC voltage from the power converter as an input and that generates a square wave as an output that is coupled to the linear AC pump to drive the arm back and forth. The pressurized air from the linear AC pump is used to inflate one or more bladders of an air mattress, for example.
