A control device of a linear compressor is provided to stably control output by preventing the output fluctuation due to variation of a power supply even when the applied power supply is varied. A control device of a linear compressor comprises a coil winding body(L), a first capacitor(C1), a capacitance converter(50), a voltage sensing unit(61,62) and a controller(70). The coil winding body is laminated in circumference direction of the linear compressor. The first capacitor has one end serially connected to the coil winding body. The capacitance converter has structure parallel to the first capacitor. The voltage sensing unit measures the voltage between both ends of at least more than one of the first capacitor and the capacitance converter. The controller induces output change of the linear compressor depending on load by controlling the capacitance converter according to voltage measured from the voltage sensing unit, and converting total capacitance of a control device.
