Abstract
An oxygen concentrator is controlled during start-up to rapidly shuttle the sieve beds between communication with the pump and atmospheric pressure, so the pressure in the sieve beds is relieved while the pump motor is starting up. After the start-up period, the sieve beds are alternately connected to the pump and atmospheric pressure for longer continuous periods.
