Abstract
In a compressor for adjusting a cooling power such that a piston integrally formed with an oscillator according to the oscillation of said oscillator adjusts the amount of refrigerant absorbed into a cylinder, a cooling power controller for the compressor which can control the cooling power by varying the power itself to change the operation state of the compressor for controlling the temperature of a refrigerator or an air conditioner, includes a power source for varying input alternate power to output the same through a plurality of secondary ports, an applied voltage controller for selecting the secondary port voltage of the power source to control the cooling power of the compressor, and a comparator for comparing a predetermined temperature with the actual temperature of an heat exchanger to control the applied voltage controller.
