Document Type and Number:
Japanese Patent JP4698577
Kind Code:
B2
Abstract:
The present invention relates to a system of controlling a piston in a linear compressor, a method of controlling a piston in a linear compressor, as well as a linear compressor, particularly applicable to cooling systems that may include, for instance, refrigerators, air-conditioning systems and the like. The objectives of the present invention are a system for controlling a linear compressor (10), the linear compressor (10) comprising a movable assembly (1), a motor (1) fed by an application voltage (VT) generating a current circulating in the motor (1'), an electronic switching device (52), and an electronic circuit (51) controlling the electronic switching device (52) to control the application voltage (VT) applied to the motor (1'), and the motor (1) driving the movable assembly (1), the electronic circuit (51) measuring an actuation phase (phic) of the current circulating in the motor (1') and a dynamic phase (phip) of the movable assembly (1) and establishing a relationship between the actuation phase (phic) and the dynamic phase (phip) determining a measured phase (phipc), the electronic circuit (51) obtaining a value of a correction voltage (VF) from the value of the measured phase (phipc) the electronic circuit (51) obtaining a value of a defined voltage (Vp) front a physical position (DP) of the movable assembly (1), the electronic circuit (51) actuating on the value of applied voltage (VT) from the sum of the correction voltage (VF) and the defined voltage (Vp). A method or controlling a linear compressor, a linear compressor and a cooling system are also objectives of the present invention.
