ABSTRACT:
An apparatus and method for controlling the output of an oxygen concentrator wherein an oxygen concentrator indicator is comprised of an oxygen sensor monitor and circuit board which receives a gas sample from the concentrator, the oxygen concentrator indicator circuit board converts the concentration of oxygen to a DC voltage range from 0 to 1 volt corresponding to 0% to 100% oxygen. A plurality of set-point amplifiers accept the voltage and feed the voltage to a logic block where the voltage is analyzed to insure that only one of a plurality of solid state relays or switches is energized at a time. A plurality of taps on an AC motor winding are selectively energized by the solid state relays to drive the oxygen concentrator at a pre-determined rate in response to the concentration of oxygen generated by the concentrator. In addition, where other types of motors are employed, such as a linear motor, similar type controls may be provided for regulating the actuation of the linear motor for generating reciprocal motion for operations of the oxygen concentrator.
