Abstract
In a driving apparatus of a linear compressor 1 having a power source capable of controlling output current and measuring output electric power, frequency of the linear compressor 1 is controlled such that the amplitude of current which is supplied to the linear compressor 1 is made constant and electric power which is supplied to the linear compressor 1 becomes maximum. With this, it is possible to drive the linear compressor 1 efficiently while following the resonance frequency which keeps varying with variation of a load. Further, a current detecting means 8 capable of detecting output current and electric power from inverter input current is provided, and it is unnecessary to newly add a current sensor.
