The invention relates to an electrically driven oscillating compressor, in particular for use as refrigerating machine, comprising a piston compressor, an electric oscillating drive for directly driving the piston compressor and a pulse shaper for supplying energy to the electric oscillating drive, wherein the group consisting of the compressor piston which is resiliently held in a central initial position, the other oscillating masses, the gas spring rate and the electric components of the oscillating drive form an electro-mechanical oscillating system whose natural frequency is at least approximately equal to the frequency of the current energizing the oscillating drive. In order to achieve an increased output-as related to the physical dimensions of the unit-and also improved efficiency and, on the other hand, the highest possible degree of independence from possible voltage and frequency variations of the supply voltage, the working pressures and other parameters, the upper dead center position of the compressor piston can be set to a predetermined value in the area of the pressure-side cylinder end, by controlling the energy content of the current pulses supplied by the pulse shaper.
